Bangkok, Thailand: The topical application of an ointment containing 2.5 percent CBD improves symptoms of psoriasis, according to the findings of a randomized, placebo-controlled study published in the Journal of the European Academy of Dermatology and Venerology.
A team of investigators affiliated with King Chulalongkorn University Hospital and Thammasat University Hospital in Thailand assessed the twice daily application of either CBD or placebo over a 12-week period in 51 patients with mild plaque-type psoriasis.
Areas treated with CBD showed significant improvements compared to areas treated with the placebo. Researchers did not identify any adverse effects attributable to the use of CBD.
“Our results indicated a trend of favorable response in the treatment with CBD, which has emerged as a therapeutic option for psoriasis,” authors concluded. “These outcomes will pave the way for future studies on [the] therapeutic effects of CBD.”
Prior studies have previously shown that CBD may reduce certain types of skin inflammation, including erythema, pruritis, and acne.
