Massage Therapy and Cannabis Topicals: More than Relaxation
Have you ever coughed or sneezed so hard that your back went out? “Slept wrong” where you wake up with a nasty kink in your neck or shoulder and have limited range of motion?
As we age, we start paying more attention to our health. Sometimes it’s because our health is not as optimal as we desire. Sometimes it’s because we see the health of the people around us deteriorate with age. We were told that if we eat right and exercise, we should live a long, healthy, and happy life. What about the stress and anxiety that comes with life? Eating right and exercising helps the physical self, but what about the mental self?
Massage therapy addresses both, offering self-care for not only the physical body, but also for the mental self. As we get older, our bodies take on the stresses of life, and we can seek massage to help us with our pain and even depression. 1 Eighty-nine percent of those who receive massage therapy agree that massage can be effective in reducing pain. 3
The primary reason people receive massage is for health and wellness such as pain management, soreness relief, tension relief, injury rehabilitation, overall wellness, and improved quality of life. As preventative care, massage therapy can help improve our sleep and our mood. Studies have also shown that massage therapy is an effective method of deflecting common seasonal challenges, 2 such as Seasonal Affective Disorder (SAD).
Cannabis and Massage
Massage therapy has become mainstream. Massage with cannabis therapeutics is the next “big thing.”
Any massage therapist living in a state with cannabis legalization or medical marijuana legislation (including CBD-only laws) can tell you about a lot of positive and promising anecdotal results from massage therapy with cannabis topicals. The “green spa rush” is becoming more mainstream, and more spas and practitioners are providing hemp or marijuana topicals in their massages.
Aestheticians are adding cannabinoids to their skin care services. Hair stylists have inquired about the potential benefits of adding cannabinoid hair products to their client services. While individual practitioners may not care, their clients are inquiring because they hear about the potential benefits people are receiving from the cannabis plant and are interested. Some may have heard the term terpenes and the entourage effect. Unfortunately, studies researching massage therapy and the use of cannabis topicals are not available. However, research which I’ll look at later in this article, is available about effects of cannabis on skin and muscles.
Cannabis sativa L. is one of the oldest plants cultivated by man. Historical records show the use of cannabis topicals to help with conditions ranging from hair growth to inflammation to skin bruises and burns. A Persian Physician, Al-Razi, was the first to report in the early 10th century that topical treatment with cannabis leaves would stimulate hair growth. 4 In the 1700s, several physicians recorded their findings with the cannabis root ball. Records indicate cannabis root ball is most often extracted with boiling water and applied topically to treat gout and arthritis 5. In the 12th century, the Persian Philosopher, Ibn Sina (Avicenna), wrote in the Canon of Medicine that “the compress with the boiled roots of cannabis decrease fever.” 6 The Argentineans also found relief of fever from malaria by using cannabis topicals that included root ball. The 18th century Persian medical text Makhzan-al-Adwiya describes topical preparations, including the leaves, juice, bark, and flowers. 7 Cannabis root has also been used topically to treat skin burns in a variety of ways, including raw root, as a juice, and mixed with fat (butter). 8
Massage Therapy Research
Massage therapy not only feel good but also IS GOOD for you. We already know about many therapeutic benefits of massage, and the benefits continue to be researched and studied. In a 2010 study, scientists at Cedars-Sinai investigated the physical effects of massage therapy. The study showed that even one massage session, boosts in the immune system, including a sizeable decrease in arginine vasopressin, a hormone that contributes to aggressive behavior; a decrease in the stress hormone cortisol; and an increase in lymphocytes—cells that help the immune system defend the body from disease. 9,10 This is proof that massage therapy should be part of your health and wellness regimen throughout your lifespan.
Other recent massage research has shown the effectiveness of massage for anything from treating pain, including but not limited to low back pain, 11 post-operative pain, 12 the symptoms of carpal tunnel syndrome, 13 pain in cancer patients, 14 pain from fibromyalgia, 15 pain from osteoarthritis of the knee, 16 and pain from rheumatoid arthritis. 17 Massage also helps reduce headache frequency. 18 Massage therapy is becoming more mainstream as people are finding it helps not only when we are in pain, but for overall wellness and quality of life.
Adding Cannabis to Massage Therapy
Throw cannabis into the picture. What do we know? The endocannabinoid system (ECS) is the largest neurotransmitter system in the human body and regulates all 11 major organ systems to create homeostasis. The ECS is a “key and lock” system, where our naturally produced endocannabinoids, and phyto-cannabinoids from the cannabis plant, are the “key” as they “lock” into the two main cannabinoid receptors 1 and 2 (CB1 and CB2).
CB1 receptors are primarily located in the brain and tissues of the central nervous system (CNS), including the spinal cord, reproductive organs, lungs, and the spleen. CB2 receptors are primarily located in the peripheral nervous system (PNS), the organs, and peripheral tissues, including our skin, muscles, and immune system. CB2 receptors help regulate inflammatory responses.
The ECS of the skin has been implicated in the regulation of skin cell proliferation, survival, and differentiation, the delicate balance of which is a key determinant of proper cutaneous homeostasis. 19 Cannabis topicals (such as lotions, creams, salves, ointments, and oils) activate CB2 receptors in the skin. This activation has been shown to help with localized pain, spasms, and various skin diseases and conditions without intoxicating effects.
These receptors are activated by phytocannabinoids of the cannabis plant. As of now there are over 200 cannabinoids. The CBD only fad has hit hard, and many do not realize CBD only has a small bell curve of efficacy. Full plant medicine is far superior than single isolate. Many of these cannabinoids interact synergistically creating an “entourage effect” 20 and affect the body in a mechanism like the body’s own endocannabinoid system which magnifies the therapeutic benefits. Explained by Project CBD, the medicinal impact of the whole plant is greater than the sum of its parts.
Terpenes vs Terpenoids
Terpenes and Terpenoids are the flavor and fragrance components common to the human diet produced in flowers, fruit, leaf and sap of plants. They are not exclusive to the cannabis plant. There are over 200 reported terpenes and terpenoids in cannabis. 21 The basics difference between the two is that terpenes contain carbon (C) and hydrogen (H), while terpenoids not only contain C and H, but also contains oxygen (O). They are the essential oils of the plant, and just like all cannabinoids, they are secreted from the trichomes of the flower. Trichomes are the microscopic, mushroom-like sticky resonated glands of the plant. Terpenoids, particularly monoterpenoids, are highly bioavailable via inhalation. 22 Terpenoids have been designated Generally Recognized as Safe (GRAS) by the US Food and Drug Administration, the Food and Extract Manufacturers Association (FEMAs), and other world regulatory agencies. They are quite potent and effect animal and even human behavior when inhaled. 23 In his review, Dr Russo, a board-certified neurologist and psychopharmacology researcher, explains that it is the phytocannabinoid-terpenoid relationship that could produce synergy with respect to treatment of pain, inflammation, depression, anxiety, and several other ailments. I will go over a handful of common terpenoids and studies behind them. The therapeutic effects of added terpenoids to a massage oil may not only come from inhalation of the fragrant molecules, it may come from penetration through the skin. 24
Alpha-Pinene, a bicycle monoterpene, is the most widely encountered terpenoid in nature. 25 Alpha-Pinene is an anti-inflammatory. 26 A bronchodilator in humans at low levels and has a high bioavailability rate of 60% absorption after human pulmonary administration with rapid metabolism and redistribution. 22
- One study found alpha-pinene is a wide spectrum antibiotic. 27
- Pinene increased mouse motility after inhalation by 13.77%. 28
- Another study found inhalation of α-pinene in mice at 10 μL/L concentration produced an
anxiolytic effect in the elevated plus maze, with general brain distribution. 29
- Chronic inhalation over 5 days, anxiolytic effects were maintained. 30
Beta-Carophyllene is common to black pepper, is a sesquiterpenoid, and is most common in cannabis extracts. If offers great promise as a therapeutic compound in dermatological applications such as contact dermatitis. 55 β-Caryophyllene synergizes with THC to impart antipruritic effects and gastric cytoprotection, and with CBD to impart anti-inflammatory benefits. 23
- One study found β-Caryophyllene is an anti-inflammatory. 31
- Another study confirmed β-Caryophyllene activity at CB2 receptors in rodent models of nociception and pain. 32
- Another study showed CB2 agonist, likely including caryophyllene, reduced cocaine administration and improved scores of depression and anxiety in animal models. 33
Limonene is a monoterpene most common to citrus rinds and is the second most widely distributed terpenoid in nature. 25 It has a high bioavailability rate of 70% absorption after human pulmonary administration. 34
- A study found limonene to be a strong anxiolytic, boosting serotonin levels in prefrontal cortex, and dopamine in hippocampus. 35
- Another study found orange terpenes, primarily limonene, boosted mouse motility after inhalation by 35.25%, while decreasing activity after caffeine 33.19%. 28
- A study done in Japan found depressed patients exposed to citrus scent experienced normalization of Hamilton Depression Scores (HADS), allowing discontinuation of antidepressants in 9 out of 12 hospitalized patients. Immune stimulation was also documented. 36
Linalool in a monoterpenoid and is commonly extracted from lavender. Linalool has established sedative antidepressant, anxiolytic, and immune potentiating effect. 37 It is also the only terpenoid that had a study focused on the percutaneous absorption from a massage oil and demonstrated the practicality of this application. 24
- Linalool decreased mouse motility after inhalation by 73%. 28
- One study found linalool is likely suspect in therapeutic capabilities of lavender essential oil to alleviate skin burns without scarring. 38
- Another study found the local anesthetic effects of linalool. 39
- Another study found in mice, an essential oil mix including linalool, limonene, and pinene, increased permeation of estradiol through the skin. 40
- Another study found a decrease in morphine opioid usage after inhalation versus placebo in gastric banding in morbidly obese surgical patients. 41
Myrcene is a monoterpene and the most prevalent terpene in modern cannabis chemovars in the United States and is anti-inflammatory. 42
- One study found myrcene is analgesic in mice but can be blocked by naloxone. 43
- Another study found myrcene sedative, used as a sleep aid in Germany. 44
- Another study found myrcene acts as a muscle relaxant in mice, and prolonged barbiturate sleep time. 45
This short list is only a little insight in the world of terpenoids. The cannabis terpenoid activity table below (Table 2) is from Dr Ethan Russo’s review titled: Taming THC: Potential Cannabis Synergy and Phytocannabinoid-Terpenoid Entourage Effects. 23 The United States is lacking clinical trials that examine the phytocannabinoid-terpenoid interactions.
Cannabis and the Skin
The skin is the largest organ of the body and the first line of defense against injury and infection and contributes to homeostasis. The skin naturally produces endocannabinoid molecules such as anandamide (AEA) and 2_AG. Phytecs, a biotechnology company researching and developing innovative approaches targeting the human endocannabinoid system (ECS), does an excellent job explaining the different layers of the skin (epidermis, immune cells, hair follicles, sebaceous glands, sweat glands, and sensory nerves) and how cannabinoids effect the ECS in each layer on the Phytecs website: http://www.phytecs.com/tour-the-ecs/the-ecs-in-skin/ .
In 2015, a multinational study showed keratinocytes are part of the peripheral endocannabinoid system. 46 Dr. Jeanette Jacknin M.D. presented at the 2018 American Academy of Dermatology annual meeting. She explained that the researchers showed a unique signaling mechanism of CB1 receptors, which has important implication in epidermal differentiation and skin development.
Several studies show the effectiveness of cannabis for a variety of skin conditions, 47 such as pruritus, 48-50 atopic dermatitis, 51-53 contact dermatitis, 54-56 acne, 56-59 and the treatment of burns. 60-61 There are also studies on how cannabinoids have helped with the treatment of melanoma, 62 anti-aging, 63 skin tumor growth, 64 pain and faster healing from epidermolysis bullosa, 65 and even cancer. 19, 66-69
One study investigated the plant cannabinoids Delta-9 tetrahydrocannabinol (THC), cannabidiol (CBD), cannabinol (CBN) and cannabigerol (CBG) for their ability to inhibit the proliferation of a hyper-proliferating human keratinocyte cell line and for any involvement of cannabinoid receptors. The results of the study showed cannabinoids, specifically CBN, have potential as a component in topical applications, inhibiting keratinocyte proliferation via, and therefore supporting a potential role for cannabinoids in the treatment of psoriasis. 69-70
Pain relief and management is on most of my clients’ minds when they come to see me. Pain usually means inflammation. As we are currently in the middle of an opioid epidemic, finding alternatives to opioids is critical. More and more studies are showing cannabis can provide pain relief without causing feelings of intoxication:
- One study found topically administered cannabinoid agonists may reduce pain without the psychoactive effects of internal consumption of cannabis. 71
- Another study found general anti‐inflammatory effects of CBD application to skin, making it a potential treatment for acne, other inflammatory skin disorders, and possibly even wound healing.19, 57
- Another study found “topical medical cannabis” helped patients with Pyoderma Gangrenosum (a rare inflammation skin disorder that causes painful sores and ulcers) heal faster from there open wounds. Also, patients felt analgesic effects within five minutes of applying the topical on the open sores. 65
- A study found topically administered cannabinoid agonists may reduce pain without the side effects of opiates. 72
Cannabis and Muscles
What about the muscles, a main concern of massage therapists? We know the endocannabinoid system is involved in metabolic regulation and glycemic control. Skeletal muscle plays an important role in metabolic regulation and glycemic control. CB1 receptors have been detected in skeletal muscle 73 and studies suggest blockage of CB1 may have direct effects on skeletal muscle modulating energy homeostasis. 74-75
Studies regarding the ECS and muscles are not as plentiful as studies dealing with the skin. You can find studies such as “The role of the endocannabinoid system in skeletal muscle and metabolic adaptation to exercise: potential implications for the treatment of obesity” 76 and studies that look at the effects of a high-fat diet and CB1 receptor blockade. 77 It is not a surprise that much less data is available on the effects of cannabis on skeletal muscles than on other tissues, given the current restrictions on research due to its Schedule I classification under the Controlled Substance Act (CSA). 78
Drawback to Cannabis Topicals
Using cannabis topicals does have a few negatives. We may not know all the ingredients in the different topicals because regulations are not standard. Ingredients may be different for hemp-derived topicals, cannabis health and beauty aids (CHABA – marijuana-derived topicals with not more than 0.3% THC in WA state), 79 or marijuana-derived topicals (stronger cannabis topicals in Washington). A person can be allergic to some of the ingredients, such as nut-based oils. Some people can be allergic to the terpenes, such as linalool.
Some cannabis-infused topicals have added preservatives or perfumes that people can be sensitive to. Unfortunately, we do not know how the cannabis was grown. Is it clean? Is it free of metals and toxins? Is it pesticide free? If not, do you want to rub it all over yourself or someone else?
Studies on the skeletal muscle ECS are not as common as studies for the skin ECS. Currently, there are no published studies on massage therapy and the use of cannabis topicals. Further studies on the entourage effect and the phytocannabinoid-terpenoid relationship are much needed and are very promising for a better future for mankind.
Anecdotal evidence suggests adults who incorporate massage therapy with cannabis topicals, that include terpenoids, into a regular and consistent health care regimen can find a better quality of life and relief from a multitude of health issues without a high feeling. Many of my fellow massage therapists’ clients are seeing their skin get “stronger” and repair itself faster. They are feeling pain and inflammation relief, so their quality of life is better without “big pharma” side effects. They feel like their muscles relax faster while on the massage table and the benefits from massage therapy last longer than without the cannabis topicals.
Massage therapy is good for you, but if you add a cannabis-infused topical to that massage, it will be an even better experience over time, physically and mentally. With all the positive experiences and possible potential, massage therapy with cannabis topicals has become intriguing and it justifies the need for future studies.
