Gentian contains three types of alkaloids, namely Gentian alkaloid A, B, and C, with Gentian alkaloid A being the most abundant. It also contains volatile oils and sugars.
- It is used in experimental arthritis to alleviate symptoms and accelerate the reduction of swelling. The mechanism is through the indirect influence on the pituitary gland via the neurohumoral system, which enhances the function of the adrenal cortex and increases the secretion of corticosteroids.
- It also has sedative, analgesic, antipyretic, hyperglycemic, antibacterial, and diuretic effects.
