Tetrahydrocannabinolic acid (THCA)
THCA is the most important ingredient in raw cannabis and is not psychoactive in its unprocessed form . THCA is converted to Delta-9-THC trough combustion, vaporisation or heating at a certain temperature, the so-called decarboxylisation. THCA, CBDA, CBDA, CBDA, CBGA and other cannabinoid acids have the highest COX-1 and COX-2 inhibitory properties, contributing to the anti-inflammatory characteristics of cannabis. This cannabinoid also acts as an anti-proliferative and antispasmodic.
