Study Notes
Gentian Root
- Constituents of Gentian root include glycosides (gentiopicroside, gentisin, and trigonelline), alkaloids (gentianine and gentianidine), and bitter principles (secoiridoid glycosides)
Fermentation of Gentian Root
- During fermentation, the glycosides are broken down into aglycones, which increases the bitterness of the root
- This process enhances the bioavailability and absorption of the active compounds
Mechanism of Action of Bitters like Gentian Root
- Bitters like Gentian root stimulate bitter taste receptors on the tongue, activating the digestive system and increasing saliva production
- This, in turn, stimulates the release of digestive enzymes, gastric acid, and bile, improving digestion and nutrient absorption
Rhizoma Rhei (Rhubarb Root)
- Constituents of Rhizoma Rhei include anthraquinone glycosides (sennosides), flavonoids, and polyphenols
- Rhizoma Rhei is used as a laxative and for its anti-inflammatory properties
Primary Use of Gentian Root
- Gentian root is primarily used as a digestive stimulant, appetite stimulant, and to relieve indigestion and flatulence
