Cannabis is a miracle herb when used topically. It behaves much like arnica and has antifungal, antimicrobial and antibacterial properties. It works wonders on bruising, muscle soreness, nerve pain, melanoma, arthritis, and any strained or sprained body parts. Used dermatologically, topical Cannabis treatment can aid eczema, psoriasis, acne, atheletes foot, and severely dry skin. Unlike ingesting edibles, topical cannabis is not psychoactive when used. It has a local effect, meaning it only affects the area to which it is applied.
