THCa (tetrahydrocannabinolic acid) topical products work by utilizing the non-psychoactive precursor to THC, which is abundant in raw cannabis plants. When applied to the skin, THCa interacts with the body’s endocannabinoid system through cannabinoid receptors located in the skin. This interaction can help modulate inflammation, pain, and other skin conditions without entering the bloodstream or causing a high. THCa topicals are often used for localized relief of pain, muscle soreness, and skin issues such as eczema or psoriasis. The anti-inflammatory and analgesic properties of THCa make it a popular choice for those seeking natural, targeted treatment options.
