Tone the digestive tract and dry up excess secretions
This particularly extensive category represents herbs that are relatively high in tannins,a chemical family that is able to denature proteins upon contact and thus are considered to have a drying tract.This action can be useful when looking to reduce excess secretions and discharges,such as in cases of diarrhea.They can also be used to tone up the bowel when it has become boggy,distended or inefficient in its contractions.
Digestive astringents are also appreciated for an ability to tighten up and heal the lining of the digestive tract as may be appropriate in cases of ulceration,food sensitivities or leaky-gut syndrome.
Digestive astringents can be mild to packering in strength and are usually best taken as a tea in combination with other herbs.Many example come from the Rosacea,or rose.family and include herbs like agrimony(Agrimonia eupatoria),blackberry(Rubus fruticosus) leaf and meadowsweet (Filipendula ulmaria).Examples of digestive astringents from other plant families include bayberry (Myrica cerifera),goldenrod(Solidago spp.)and plantain (Plantago spp.)
