The tannins contained in the rhizome form insoluble bonds with various proteins of the superficial cells on mucous membranes, resulting in a compaction of the surface. In the intestine and oral pharynx, this makes it more difficult for toxic substances, bacteria and viruses to penetrate, and inflamed or injured areas heal more quickly.
In the intestines, fluid leakage into the bowel is reduced, so that the stool becomes firmer again. Tannins are also responsible for the red coloration of the fractured areas of the rhizome, as they are transformed into colored compounds when exposed to air.
Furthermore, a blood sugar and blood pressure lowering effect has been observed, which could be due to the triterpenes.
Bloodroot: side effects
In rare cases, stomach discomfort may occur in particularly sensitive patients.
Bloodroot should be used internally for a maximum of 3-4 days and externally for a maximum of 2-3 weeks at a time, otherwise the kidneys and liver may be affected.
Possible interactions
Taking bloodroot and other tannin-containing plants may possibly reduce the effectiveness of other medicines taken in parallel. Therefore, these should be taken about two hours before taking tormentil rootstock.
