Cannabis-Based Medicine: A Breakthrough For Healing Intractable Chronic Wounds

Chronic wounds disproportionately affect older adults, severely impairing their health and quality of life. Aging diminishes our capacity for healing, and conditions such as diabetes, vascular disease, cancer and surgical procedures put elder adults at further risk of developing chronic wounds.

While notoriously difficult to heal, a new, experimental cannabinoid-based treatment promises to vastly improve the prognosis for the millions of older adults who suffer from chronic wounds.

A Multi-Billion Dollar Market

According to the American Professional Wound Care Association, non-healing wounds impact some 15% of Medicare beneficiaries, and the costs associated with treating them can reach $30 Billion.

The anti-inflammatory properties of cannabinoids are driving investigations into potential therapies for an entire spectrum of disease states, and treatment for chronic wound healing is one of them.

Results of a recently completed study found that an experimental cannabinoid-based topical medicine achieved an extraordinary 90% success rate in healing chronic wounds. Dr. Vincent Maida, a palliative medicine specialist at the University of Toronto and principal investigator of the study, recruited thirty patients in an open-label study testing his proprietary Topical Cannabis-Based Medicines (TCBM). Twenty-seven of the participants achieved complete closure of wounds that, in some cases, had resisted healing for over a decade.

Cannabinoids for healing

Dr. Maida has been investigating cannabinoids for treating pain and wounds for over 20 years. During a graduate program on wounds at University of Toronto’s Dalla Lana School of Public Health, he encountered a pre-clinical study showing evidence of the efficacy of cannabinoids for wound healing. He recalls: “My supervisor thought I was off my rocker that I thought that cannabinoids could be effective for treating integumentary (the skin and mucous membrane system) and wound conditions. Since then the basic science has been catching up and validating all of my research.”

The Feds Are Coming For Delta-8 THC

He recalls: “When I started recommending cannabinoid therapies to my patients, I was considered a heretic.” But when Canada broadened the definition of medical cannabis to include extracts as well as dried botanical flower, Dr. Maida developed and patented his own formulations, and started to recruit patients for his study. He now holds what he claims to be the world’s first patents on Topical Cannabis-Based Medicines (TCBM) indicated for Integumentary and Wound Management.

The worst of the worst

Dr. Maida runs a tertiary wound clinic in the Toronto area, where he receives referrals of the most severe wounds in southern Ontario. As he explains, “Everyone else’s failures come to me. I get the worst of the worst.”

Through his recent study, he was able to subject some of those recalcitrant wounds to his innovations and intellectual property. And according to Dr. Maida, “I’m having results that are just absolutely mind-blowing.”

“I’m actually the first on record worldwide to start applying cannabis products to wounds to help with pain management, and now showing that it can heal the unhealable wounds in very elderly and sick patients. I’m literally healing wounds that otherwise people would be dying from or dying with… When I show the before and after pictures, people can’t believe that these results are real – but they are real!”

“So if I’m able to heal the worst of the worst, imagine what my innovations can do for everyday burns and scrapes and so forth.”

Anti-inflammatory, lipophilic agents

Chronic inflammation is at the heart of a non-healing wound. Normally a wound progresses through an orderly cascade of phases from the time of initial trauma until it is fully healed. As Dr. Maida explains, wounds that don’t heal get stuck in the inflammatory stage. “There’s ample pre-clinical information already published that THC and CBD and other elements of cannabis extracts have anti-inflammatory properties. My cannabinoid-based medicines are rebooting the wound out of that chronic inflammatory stage.”

“The other thing that made me realize that wounds and cannabis were going to mix is that intact skin is hydrophilic, but a wound, on the other hand, is lipophilic. That kind of tissue can absorb THC and CBD which are also lipophilic. So it’s a perfect fit. This was one of my epiphany moments: that the very molecules that are anti-inflammatory in the cannabis extract are going to be able to be absorbed rapidly into a wound bed.”

“So everything is lining up. The endocannabinoid system (ECS) is present in the integumentary system which is the largest organ of the body. And there’s a huge opportunity to activate the ECS through the integument, and promote things like healing wounds and relieving pain from wounds – because when you heal a wound, the pain goes away.”

A partner for the next stage

At this point, Dr. Maida is looking for a partner to help take his proprietary IP to the next level, and get his products on the market to help millions of people.

According to Dr. Maida, much of the money and effort spent on treating chronic wound is in vain. “One of the areas with the worst outcomes is wounds – in terms of pain relief and healing, the results are dismal. We’re spending billions and spinning our wheels.”

Until now, Dr. Maida has self-funded the R&D of his proprietary therapies. And he believes that, seeing patients with chronic wounds week in and week out, with no prospect of improvement, was what drove him to make the personal and financial sacrifice, to give his patients hope.

The follow-up randomized controlled study is already designed and waiting. At this point, all he needs is a partner with the resources to help launch it. “It’s really what’s driving me – at a time when my colleagues are retiring, I am working on probably the greatest project in my entire career.”

Sponsored – The New Neosporin? — How CBD May Speed Up Wound Healing

Over the past several years, people have started raving about the benefits of CBD. From anxiety relief to pain reduction, CBD oils have proven to be useful in treating internal ailments. However, dozens of dermatologists are getting interested in CBD’s skincare benefits. In fact, recent research suggests CBD may naturally shorten wound recovery time. If these studies are valid, it could lead to a breakthrough in treating a wide range of wounds.

This could lead to a huge breakthrough for treating many common injuries. Dog bites, for example, can cause a wide range of wounds. The most common dog bite injuries include puncture wounds, scarring, and infection. Clinical trials are suggesting that using CBD based products can reduce the inflammation and reduce scarring.

CBD For Scars — What Does the Science Suggest?

One of the most in-depth studies examining CBD for wounds took place in Brazil in 2018. Researchers from the University of São Paulo gave mice scars on their tongues and injected a few with either 5 mg or 10 mg of CBD per day. To keep this study well-controlled, a few of the mice received a placebo shot.

Interestingly, the mice that received CBD showed a greater improvement in wound healing versus the control group. Specifically, scientists say the CBD mice had lower signs of inflammation, which may have helped promote tissue healing. It’s worth noting, however, that these effects weren’t noticeable until the seventh day.

Further evidence out of the University of Modena seems to support the findings in the Brazilian trial. In this Italian study, dermatologists observed the effects of topical CBD on a group of patients with surgical scarring or psoriasis. At the end of the trial, researchers found those who applied CBD topicals twice per day had a noteworthy reduction in skin inflammation. Once again, this suggests CBD exerts a healing, anti-inflammatory effect on wounds.

How Can CBD Heal a Wound?

Like the nervous system or the digestive system, the endocannabinoid system (ECS) is a natural part of our biology that plays many roles. Interestingly, the body’s ECS produces natural “endocannabinoids” that constantly strive to create a sense of balance. To date, cannabis is the only plant we know of with phytocannabinoids like CBD that interact with the ECS.

So, what does this have to do with our skin? Well, researchers now believe the ECS’s cannabinoid receptors extend to our skin layer. This means when you apply a CBD lotion, local receptor sites should absorb this cannabinoid. While CBD won’t penetrate your bloodstream via your pores, it may have a localized anti-inflammatory effect.

How Should People Use CBD for Wound Healing?

While all of this research into CBD and skincare is interesting, there’s still a great deal we don’t know. Also, using CBD creams is no excuse for not seeking professional medical care, especially after a severe injury like a dog bite. Anyone who has a wound should seek medical assistance ASAP. If you want to use CBD as an adjunct therapy, be sure to run it by your doctor to be on the safe side.

Does Cannabis Help Heal Wounds and Injuries Faster?

Cannabis has been used to treat topical wounds such as cuts and burns for millennia. Now, modern research is investigating the science behind cannabis’ ability to treat topical injuries and is discovering exactly how vast a role the endocannabinoid system plays in the maintenance of healthy skin and wound healing.

Cannabis and wound healing in history

Historical medical texts of various different cultures mention the use of cannabis in topical preparations to treat cuts, scrapes, and burns. For example, Egyptian papyri note the use of topical antiseptic preparations thought to be made from cannabis mixed with fat. And Greek writers from the 1 st century BCE record the use of cannabis to treat horses suffering from wounds and sores, as well as to treat nosebleed in humans.

The medieval French herbalist, Ruellius, recorded in his 1536 treatise De Natura Stirpium that cannabis extract could be used to treat wounds and ulcers. Then a few decades later, the renowned German botanist, Tabernaemontanus, recommended a mixture of butter and cannabis leaves to be applied to burns.

In 1649, the eminent British herbalist, Nicholas Culpeper, recorded that cannabis could be used to treat burns and bleeding, due to its antiseptic properties. Finally in 1751, British herbalist, Thomas Short, wrote in his Medicina Britannica that a preparation of cannabis could be used to treat burns, wounds, insect bites, and ulcers.

Modern research into wound healing & cannabis

In more recent times, researchers have investigated the ability of cannabis and cannabis preparations to reduce pain, swelling, and bleeding associated with cuts and burns, and to aid in the repair of epidermal tissue.

Research conducted so far has provided ample evidence that cannabis has a strong analgesic, anti-inflammatory, and antiseptic effect. It very much appears that the endocannabinoid system is fundamentally involved with the process of healing itself and has a vital role to play in the formation of scar tissue.

Wound healing & the endocannabinoid system

The endocannabinoid system plays a major role throughout the entire process of wound healing. Immediately after an injury occurs, levels of anandamide in the affected tissues rise and provide an analgesic effect by acting on the CB1-receptors present in the peripheral nerves.

A 2010 study conducted at the University of California found that if a synthetic compound known as URB937 was administered to rats and mice with peripheral injuries, levels of anandamide increased and the analgesic effect became stronger. URB937 exerts this effect by inhibiting the fatty acid amide hydrolase (FAAH) enzyme, which is responsible for the degradation of anandamide.

Another 2010 study conducted at the China Medical University found that in mice inflicted with skin incisions, the number of cells expressing CB1-receptors increased at the injury site. The increase in CB1-expressing cells began six hours after injury occurred, peaked at five days post-injury, and reduced to baseline levels by fourteen days post-injury.

At first, the majority of new CB1-expressing cells at the injury site were mononuclear cells (such as fibroblastic cells and specialized immune cells known as monocytes) that are known to mediate inflammation and the immune response. After several days, fibroblastic cells (which are vital to wound healing and scar formation) began to dominate. While it is not clear exactly what mechanisms are at work, it is evident that anandamide and the CB1-receptors are involved in the process.

Cannabis & wound healing in the internal organs

As well as wounds affecting the epidermis and cutaneous tissue, the endocannabinoid system has a role to play in the healing of injuries to the internal organs, particularly to the epithelium (the smooth layer of cells lining the surface of organs and other bodily structures).

In the human colon, the epithelial tissue expresses both CB1 and CB2-receptors. In normal tissue, CB1-receptors are more commonly expressed, and in abnormal conditions (such as in individuals with inflammatory bowel disease) CB2-receptors begin to dominate. The CB1-receptors are routinely involved in the closure of wounds to the colonic epithelium; if damage is chronic, CB2-receptors become crucial to ensuring that excess scarring does not occur.

In the corneas, injury to the epithelial tissue causes the local release of endogenous cannabinoid and vanilloid receptor agonists that are believed to assist in the process of wound-healing. In a 2010 study, researchers treated human corneal epithelial cells in vitro with WIN55,212-2 and capsaicin—a CB1-receptor and a vanilloid-receptor agonist—to determine the role each receptor played.

They found that activating either receptor led to the transactivation of the epidermal growth factor receptor, which is vitally important for the regeneration of damaged epidermal and epithelial tissue.

In periodontal tissue, an upsurge in cells expressing CB-receptors was also observed immediately subsequent to injury. An increase in anandamide levels in patients who had just undergone periodontal surgery was also noted.

Administration of AM251 and AM630, synthetic selective antagonists of the CB1 and CB2-receptors respectively, was observed to cause significant reductions in gingival fibroblast numbers. This suggests that agonists of the CB-receptors promote fibroblast proliferation and therefore expedite wound-healing.

How Does Cannabis Help Chronic Skin Conditions?

Cannabinoids & cirrhosis of the liver

In the liver, chronic tissue damage and inflammation (such as that caused by alcoholism or hepatitis) promotes the wound-healing response, causing fibroblast cells to migrate to the damaged area and begin the process of fibrosis (scar formation). Over time, the overproduction of fibrous connective tissue causes cirrhosis and inhibits the liver’s ability to function normally.

When this happens, we once believed that the presence of anandamide in high levels could increase the rate of fibrosis and therefore the severity of cirrhosis. However, more recent research shows this may not be the case. We do know that anandamide is an agonist of the CB-receptors, though. So, the presence of an antagonist such as cannabidiol could block the effect and slow the rate of fibrosis.

A 2006 study on mice published in Nature Medicine demonstrated that administration of a synthetic CB1-receptor antagonist, SR141716A, inhibited the wound-healing response to acute hepatic injury, and slowed progression of cirrhosis in fibrosis injury — supporting the idea that CBD and similar antagonists can help to treat cirrhosis.

The CB2-receptor & hepatic wound healing

Interestingly, the CB2-receptor has its own unique role to play in the onset and progression of fibrosis in the liver. Usually present in lower concentrations than CB1-receptors, their numbers increase dramatically during fibrogenesis (production of fibrous tissue) and after injury.

The study linked to above showed that for mice genetically modified to lack CB2-receptors, fibrosis was significantly worsened — indicating that presence of CB2-receptors in typical mice inhibits fibrogenesis. It is thought that the CB2-receptors exert this effect by causing apoptosis (programmed cell death) of the fibroblasts.

It appears that when CB2-receptors are limited in number or absent, the fibroblasts can accumulate, and fibrous tissue can thus build up more rapidly.

Hemp seed oil for wound healing

Although hemp seed contains no cannabinoids (except residual traces from the production process), it may be useful in treating burns, cuts, and other external wounds. This is due to its unique balance of omega-3 and -6 essential fatty acids, which are present in optimum levels for human health.

Although very few formal studies have been done into the ability of hemp seed itself to treat topical injuries, there have been multiple papers written on the ability to improve wound-healing of essential fatty acids in general. There has also been one clinical trial into the uses of topically-applied hemp seed oil, which concluded that it had a good ability to heal mucosal skin wounds after eye, nose, and throat surgery.

Therefore, cuts, burns, lacerations, and other similar injuries may be treatable both with hemp seed oil and with cannabinoid-rich cannabis preparations. For those looking for a safe way to use CBD, Sensi Seeds has a couple of CBD-products on offer. One of them is CBD oil: a food supplement that contains different phytocannabinoids, with the most well-known being CBD, CBC (cannabichromene), CBG (cannabigerol), and CBN (cannabinol).

For injuries to internal tissues or organs, cannabinoids have a definite role to play, but further investigation is required so that targeted therapies can be developed. With such a complex and finely-tuned system, incorrect dosages or cannabinoid ratios could cause the opposite effect to the intended one.

anyone have a problem with scar tissue on the small intestines creating a blockage and used the Marijuana treatment to eradicate it or open the blockage?

My mom is bedridden and is currently being given standard medical care for a wound on her coxcyx. The wound isn’t really improving much and I’d like to know if anyone has had any luck treating deeper wounds with cannibis oil . Thanks

How about this for cannabis I was hopelessly addicted to OxyContin from severe back injury, I started growing, extracting, and processing the RSO. At YouTube, Doctor Otis demonstrates how Rso absolutely killed melanoma. Oxy craving lasted two weeks, no rehap thanks to Rick Simpson oil.

My sis had two bed sores on her foot large and on her heal, we put cannibus oil on the bandage and both are completely healed. I changed the bandage every three days for about 11 days then just waited till the scab fell off

Does anybody have experience in using cbd or hemp products for treating bedsores (pressure or decubitus ulcers)? Please let me know!!

Just surfing CBD oil and came upon this site. I was wondering if there has been any research on using CBD oil/cannabis in animals, particularly in horses. I have a horse that I have been treating for corneal ulcers, and we have gone through several topical antibiotics since April of this year. I’ve heard so many people say they have found pain relief, etc., from the CBD oil, so I thought it would be worth inquiring about for my horse. Thanks for any information you can give, or perhaps suggestions for veterinarians who are using CBD oil as a treatment in animals, especially horses.

I got some mysterious bites from a recent mulch job at home. I’ve been suffering for 4 weeks. I’ve seen 7 Dr.s and 12 medication and I am still not thru this. Is there something I use like CBD for healing or ridding me from these painful bites?

Thanks for your comment, I’m sorry to hear about your condition. As Sensi Seeds is not a medical practice, we cannot give any medical advice I’m afraid. You caould try showing this article to your medical practitioner? Sorry I can’t help you further, good luck!

With best wishes,

My brother has a stage four pressure sore on his buttock for over two years. Cannot seem to get it to heal. Lots of infections, anemic and low protein.
I want to include CBD oil through his feeding tube to start on internal healing. Is CBD oil better option than Hemp seed oil? Any one had first hand experience with this?

Great blog! Thanks for your very grateful post, it’s really helped me a lot more to know about my website. I was impressed with your article, it’s a knowledgeable story about it.

I discovered parts of this text (mostly theory at the time) as much as 40 yrs. past. For varied ails, I have researched and used herbs all my life. This won’t qualify me as a healer, but next time a cut like this, mix a little Symphytum (wild) with clean weed powder and massage with daily. May not even scar! In U.S., I live in region 6. Try to find NW woods dirt.

ihave a venous ulcer on my right ankle for over 25 years its healed temporally then open again.I have tried every none procedure there is available ablations,stents,apilgrafts,skingrafts an even a wound-vac nothing seams to work.I eat a high protein diet consume a large amount of vitamin C,zinc,magnsium.This why I’m extremely interested in hemp oil cannabis oil helping with my condition.Looking for imformation an help

25 years! I’ve been going strong for 7 years with mine and am in the same boat. I’ve been through every possible treatment and surgery. Wound care clinics are absolute hell. This seems to be the holy grail of information when it comes to cannabis treatment. So far all I can find is proof that it can be done, but no one will say how to do it. At my last dr appointment I was told I need to consider amputation. Cannabis is my only hope. If I find an answer, I will definitely come back and tell you.

We are sorry to hear about your condition. As we are not medical practitioners we cannot give medical advice, but we have made a post aimed at medical professionals who might not know where to start when their patients mention cannabis; there is also this post on cannabis and skin conditions which you may find interesting if you did not see it already.

With best wishes,

None of you know me my name is Sharon and for the last 27 years I have been dealing with chronic venous insufficiency caused from a blood clot which I ended up getting after I had my son, but I didn’t find out until it was in my lungs. To make a long story short I also have had a few venous stasis ulcers on my right ankle and lower leg that healed and reopened, and the doctor that I been seeing told me that a regular wound doctor only focuses on healing the wound on the outside and they dont focus on what the issue is on the inside, and I found that with time that I finally got off from work the ulcers have made some progress in healing after having these newer ulcers going on 5 years now, and my husband asked me if the pot i have been smoking is actually helping with healing, also my neighbor/friend gave me some cactus cbd/hemp oil that you put under the tongue. Haven’t seen any results yet from the oil but keeping my fingers crossed.

And another thing I have been through a lot of pain while dealing with these ulcers

I have been treating a venous ulcer with 50/50 cannabis oil and coconut oil, a few times a week, and it seems to be helping. but is still very slow to heal. it burns and itches a little when i apply it, and it seems to melt all the scabs and dead skin away, and leaves a clean hole where the ulcer is. im not positive its helping but it sure isnt hurting..

I’m using the same mixture on mine. I’m not sure if it’s helping or not, but that cannabis does help with overall pain once the initial sting goes away, so that’s a plus. Best wishes to you!

CBD Canabidiol oil has no THC well maybe 0.04% nothing is a 100%. That is very little. So it is safe and I’d give it to my kids. And also it’s a great protein.

Sorry for typo in my email address in previous post. I had “ii” in umich

This is fascinating! I have had two conditions that relate to this article. I hope others will share any insight they might have to further knowledge about strains and dosage, especially for scar tissue.

1. About 10 years ago I had a vascular ulcer near my ankle. After diagnosis, my husband packed cannabis leaf and hemp oil into the wound at bed time. Each morning the hole, the size of a 25 cents piece, got smaller until it completely closed 5 days later. Though healed, I followed through with a referral to a retired vascular surgeon, who was then consulting with patients diagnosed with this condition. He and his staff told me there was no cure for vascular ulcers, except rest and elevation of the leg and that it takes months to years to heal. While they were ecstatic about my healing, I doubt they ever shared this with their patients. This article explains how the hemp poultice could have worked.

2. In Oct 2011 I had TKR of the left knee. I never gained more than 90 degrees range of motion even with manipulation under anesthetic. By this time I was a medical marijuana patient using a cannabis cookie nightly. One cookie or less kept me from waking up in arthritic pain at night. I consumed no more than that until Sept 2013 when my arthritic pain flared up and my range of motion was at an all time low. I discovered that CBD-rich raw cannabis juice eliminated most of my chronic pain and improved the functioning of my left knee. I continued to workout 10-12 hours weekly with prescribed exercises until I injured my left knee on an unprescribed machine. Because of extreme scar tissue, from the surgery, the prescribed exercises, and the injury, I have a lot of pain and dysfunction.

This article makes me wonder (should I find an orthopedic surgeon who will operate on my right knee) if higher doses of cannabis after TKR could prevent extreme scar tissue formation? After my injury on the exercise machine, I did breakup a lot of scar tissue in a warm water pool especially with Ai Chi. If I have surgery again, aqua therapy only (no weight machines) and the proper cannabis dose could make a huge difference.

I have the same ulcers and my leg is about to be amputated. I’d like to know exactly what you used and how you did it please. This is my last hope.

Hi Amy my name is Sharon I also been dealing with ulcers (chronic venous stasis ulcers), and they got infected so now I am on antibiotics, and I finally was able to take time off so I can heal. I also been wanting to find something that will heal these ulcers for good so I started smoking pot and just recently started taking prickly pear cactus hemp/cbd oil hoping with that and continuing time off I will have my ankle back

Hi i have leg ulcers and have suffered from them for about 6 years ive just got some oil n cocnut oil caps. im going to this on to my ulcers. I just wanna no how u applyed it n how long u left it on each time.

Hi I use cannibus for a spinal injury. I use it for muscle spasms, pain, anxiety, and motivation. About a year ago I got a pressure ulcer that got infected. I have had wound care for about a year now. My wound is healing slower than ever now. I would like to know more about using cannibus to heal my wound.

Thank You,
Brandon Gallagher (cannibus supporter and believer that this plant heals)

I hope you tried this and it worked. My dad has has a diabetic ulcer on the heel of his foot almost four years ago. After trying something, it working for a month or so, then it stopping, trying something different and getting the same thing..working and stopping…I was beginning to think my dad would be dealing with this for the rest of his life and it sucked. About a month ago, we were given some cannabis lotion to try. The difference​ after the first time using it on the wound was really good, so we started using it twice a day and the difference in a month is absolutely amazing!! Doctor said looks better than it ever has. I definitely recommend using it if you ever get a wound.

I’m a trucker with 3 bad ulcers/open wounds. I read your story. I have a stick of tch salve. I pray this works for me.
