Learn about the newest studies con CBD & Psoriasis and how CBD’s action on our Endocannabinoid system and anti-inflammatory action could relieve psoriasis.
Cannabinoids like CBD, THC and CBG have shown an array of promising properties for skin afflictions like eczema, atopic dermatitis, acne, itch and rosacea, as well as for psoriasis.
CBD (Cannabidiol) is a promising cannabinoid with, to name a few, regulating, analgesic, anti-inflammatory, antipruritic and antioxidant properties.
Though CBD research is still very young, many researchers are excited about it’s myriad of properties, internally and externally used, to treat pathologies from anxiety to cutaneous conditions like psoriasis. In this article we will briefly explain the findings on CBD & psoriasis and how this hemp-derived cannabinoid could be used as a treatment to regulate and relieve symptoms of this skin affliction, which to this day still has no known cure.
Psoriasis is a chronic, genetically predisposed, but environmentally triggered auto-immune disease which affects our skin. It is characterized by inflammation caused by an erroneous response by our immune system. The inflammation commonly appears as red and scaly plaques. According to the World Psoriasis Day consortium, psoriasis affects almost 2-3% of the world population.
Psoriasis is a severe skin disease which, according to statistics collected by the World Psoriasis Consortium, negatively affects the quality of life of 60% of those with this disease (1).
Psoriasis is caused by an overactive immune system that speeds our skin cell growth (or turnover), also known as dysregulation of keratinocyte differentiation or hyperkeratinization disorder. Healthy skin cells usually grow and shed throughout a month’s time, giving space for new skin cells.
However, psoriasis speeds skin cell differentiation to up to 3-4 days not giving the skin cells enough time to shed. Skin cells thus accumulate and create plaques that are not supple like healthy skin but instead crack and break open leading to irritation, itching, stinging and burning.
The most common spots for psoriasis are the elbows, knees, and scalp, however, psoriasis can appear in any part of the body. According to the National Psoriasis Institute, psoriasis can manifest itself in two peaks, the first being between the ages 15-25 and the second between the ages of 50-60. These two age groups happen to be prominent hormonal/endocrine shifts as well…food for thought. There are a variety of different kinds of psoriasis:
Currently the most common treatments for psoriasis, according to Mayo Clinic, are:
*Systemic therapies can have very severe side effects
In the last 50 years scientific research on Cannabis has grown quickly, starting from Mechoulam’s synthesis of CBD & THC to the discovery of our Endocannabinoid System in the endocannabinoids in the 1990’s.
CBD’s anti-inflammatory, antipruritic(anti-itch), antioxidant, antitumoral and analgesic properties have sparked interest in researchers’ as an alternative or complement to traditional treatments. Offering fewer side effects, helping prevent flare ups and managing pain and discomfort.
As usual, the best explanation will start with our Endocannabinoid System.
The skin is an extremely important and overlooked organ, it’s crucial in protecting ourselves from external factors. It also is a part of our neuro-endocrine immune network (a network connecting our nervous, endocrine, and immune systems), which, surprise surprise, our Endocannabinoid System (ECS) regulates.
This means that stimuli received by our skin can influence our endocrine, immune and nervous systems, which can all be regulated by our ECS. New data shows that most cells in the skin highly express cannabinoid receptors and suppression of skin inflammation is considered a leading function of dermal ECS.
Cannabinoids may be involved in the modulation of our skin’s functions through our neuro-endocrine immune network, however, their role in dermatological conditions is still unclear. (2)
What many studies have pointed to is that the Endocannabinoid Systems’ unbalance or dysregulation could be a key factor in dermatological afflictions.(3) Raphael Mechoulam, the father of cannabis research, said it as well, “The endocannabinoid system is very important. Almost all illnesses we have are linked to it in some way or another. And that is very strange.”
Studies have indicated that an imbalance or dysregulation of the Endocannabinoid System could be a key factor in dermatological conditions.CHECK OUT OUR PRODUCTS
This has led researchers to investigate the possible use of cannabinoids for relieving serious cutaneous conditions including; Atopic Dermatitis, Eczema, Acne Vulgaris and Psoriasis.

In the last 15 years there have been more clinically backed trials to investigate CBD’s potential use as a treatment for psoriasis. At the moment there are four interesting ways that CBD has been researched to help in psoriasis treatments.
At the moment there are a variety of clinical trials underway, most topical and internal. According to M.D. Hervé Damas, “Depending on the severity of the disease, I will use either topical creams or a combination of topical and systemic treatments.”
There are ongoing trials like the double-bind randomized trial taking place in Aalborg University in Denmark to relieve Arthritic psoriasis in hands. This particular case has been using ingested 10 mg CBD tablets, once a day for two weeks and then 2 times a day for 2 weeks and if results are not presented 3 times a day, a total of 30 mg.(8)
There have also been clinical cases with different ointments and salves. In a study completed in 2019 Israeli study, completed in 2019, they used a combination CBD & THC to study to the maximum dose possible, sadly the results have not been shared. (9)
In another 2019 study conducted in Italy, CBD-enriched ointments were used to study the anti-inflammatory effects and possibilities of improving the quality of life in patients with dermatitis (5 patients), psoriasis(5 patients) and cutaneous scars(10 patients). The results were optimistic however with such a small sample size, and no placebo control, it’s hard to find conclusive evidence.(10)
One of the most interesting studies for psoriasis and CBD is in the treatment of Arthritic psoriasis.
Nearly 1 in 3 people with psoriasis will develop Arthritic psoriasis in their lifetime. The inflammation caused by psoriasis can affect different organs and tissues of our body, and it can especially affect our joints, causing inflamed and stiff joints, resembling arthritis. Treating PsA early on can help prevent permanent joint damage.
CBD’s analgesic and anti-inflammatory activity can calm and relieve pain inflicted by arthritic psoriasis.

CBD can help relieve symptoms and regulate our immune system, however some forms of psoriasis are extremely severe and research is still lacking to support the sole use of CBD to help these forms of psoriasis.
At the moment the most we know on this subject is that not using your prescribed medication while using CBD can cause flare-ups to come back and at the moment CBD has not been researched enough to prove to be functional alone, in severe cases.
So if you have decided to use CBD to treat psoriasis, here is how to do it safely.
Based on current clinical trials, it seems as though CBD is best to be used internally* and externally. Ingested use, or internal use which reaches the bloodstream, could be done with a tablet, a transdermal patch or with CBD oils, sublingually. Sublingual administration is one of the most common uses of CBD oils for its rapid effect, as it reaches the bloodstream quickly. Topical application will not reach the bloodstream but can offer much-needed relief. CBD enriched ointments and salves can help as well as oils. *Internal use is not regulated in Spain, however is quite common in places like EEUU and the UK.
According to the conclusions of a study from the Alborg University in Denmark, one could start with 10 mg a day and raise the dose, from once a day to twice a day after 2 weeks. Topical application, seen in CBD enriched ointments, salves, and oils will not reach the bloodstream but can offer localized relief.
CBD nor any medication are cure-alls and should always be accompanied by complementary habits. The Mayo Clinic’s list of complementary therapies is a great way to start implementing habits that could help relieve psoriasis symptoms:
CBD can have interactions with certain medications due to its inhibition of an enzyme, responsible for metabolizing certain medications. One should also always check with their doctor to make sure there are no interactions between their current medication and CBD.(10) It is also important for anyone that is pregnant or breastfeeding to discuss CBD use with their doctor as CBD can cross the placenta and can accumulate in breastmilk. (12)
CBD’s known side effects are known to be low to moderate and include: drowsiness, dry mouth, dizziness and loss of appetite.
At the moment, like most data on CBD, it is too early to make conclusive claims however what is clear is that CBD and other cannabinoids pose a promising future for certain dermatological diseases, especially those which are auto-immune and cause inflammation.
At the moment some experts see a bright future, however many others are skeptical. Jordan Tishler, MD and physician said to Health Magazine, “The effects of cannabis are relatively weak compared to topical steroids like hydrocortisone.
In short, at this time I would not recommend any topical cannabis or CBD products to treat a serious illness like psoriasis.”
However, others have been granted patents to continue the study and use of cannabidiol and even other cannabinoids, like Cannbigerol, CBG. In 2019 Lekhram Changoer Lekhram and George Anastassov were awarded a patent for their topical six-week treatment of CBD & CBG.
We can hope that studies will continue so we can have more information about this up-and-coming cannabinoid and the many other promising substances that the Cannabis Sativa L plant has to offer! We can hope that studies will continue so we can have more information about this up-and-coming cannabinoid.
