The Rosette THCA Acid tincture is non-intoxicating and has a very high terpene and antioxidant content. THCA is the acid-based precursor compound to THC, found in the raw cannabis plant. THCA has its own unique properties separate from the more commonly known THC properties. THCA has been found to have powerful anti-inflammatory, analgesic (pain reliever), neuroprotectant and antispasmodic properties.
