Christopher Hobbs:
“Rhatany is an astringent herb used externally for gum problems (sore, spongy, red) and internally for sore throat (as a gargle), diarrhea, and hemorrhage. It is applied locally for hemorrhoids and wounds. Rhatany is one of the more powerful herbal styptics and can be applied to a cut or extracted tooth to stop bleeding.
Try brushing the gums with 10 drops of rhatany tincture in a little water. A few commercial herbal mouthwashes contain rhatany as an ingredient, possibly blended with myrrh, propolis, echinacea, or other herbs.
Rhatany has a taste of BITTER, ASTRINGENT and a temperature of COOL.”
Historical Uses:
Rhatany, native to South America, has been used traditionally for its astringent properties. Indigenous people and early herbalists used its root extract to treat wounds, diarrhea, and oral issues such as gum disease and mouth ulcers. It was also employed as a dye and in cosmetic formulations due to its red pigment.
Modern Clinical Uses:
Today, herbalists and naturopaths use rhatany primarily for its astringent and antimicrobial effects. It is included in oral care products, like mouthwashes and toothpaste, to help manage gingivitis and canker sores. It is occasionally used in herbal remedies for digestive issues and hemorrhoids.
Chemistry:
Rhatany roots contain tannins (notably ratanhins), lignans, and flavonoids. These compounds contribute to its astringent, antioxidant, and antimicrobial properties. The plant also produces alkannin derivatives, which give its characteristic red color.
Pharmacology:
- Astringent Effects: The high tannin content constricts tissue, reduces bleeding, and promotes healing.
- Antimicrobial: Rhatany extracts inhibit bacterial and fungal growth, especially in the oral cavity.
- Antioxidant: Flavonoids provide some protection against oxidative stress.
Clinical Trials
Modern clinical trials are limited. Most evidence supporting its efficacy comes from traditional use and preliminary in vitro studies demonstrating its antimicrobial and astringent properties. Limited human studies have suggested effectiveness in managing oral health issues like gingivitis and stomatitis.
Summary
Rhatany is valued for its astringent and antimicrobial properties, particularly in oral and skin health. While traditional and preliminary scientific evidence supports its use, modern clinical trials are sparse, and more research is needed to establish standardized dosages and long-term safety profiles.
