Healing Properties and Warning

The rhubarb plant root contains anthraquinonic derivatives (free anthraquinones and glycosides), to which the plant owes its laxative and purgative properties, and tannin, which gives it astringent, stimulating, and digestive properties. Its effects depend on the dose taken:

1. Low doses (0.1-0.5 g of root powder or half a cup of infusion): Tannin’s astringent properties predominate. It stops diarrhea, increases appetite, and stimulates the functions of the stomach (eupeptic: it promotes digestion) and the liver (choleretic: it relieves liver congestion and encourages bile secretion). In short, it invigorates and regulates the digestive system.
2. Medium doses (0.5-1 g of root powder or a cup of infusion): Anthraquinones’ Laxative properties predominate. Some 8-10 hours after intake, they produce defecation with no colic. They also present a powerful congestion-relieving effect on the liver.
3. High doses (1-3 g of root powder or 2-3 cups of infusion: Effective purgative and vermifuge.

WARNING! Continuous use of rhubarb can produce colitis, an inflammation of the colon or large intestine. We advise against its use in the following cases:

1. Pregnancy, menstruation, and hemorrhoids produce blood congestion in the pelvic organs, a severe problem in these cases.
2. Kidney stones have a high amount of oxalate, which forms part of kidney stones.

1. Chinese rhubarb or turkey rhubarb (rheum palmatum L.).
2. Rheum rabarbarum L. = Rheum undulatum L. originated in Asia and has spread throughout Europe and North America. Its petioles are edible.
