Astringency - Definition


Astringency denotes a capacity to contract mucus membranes. Certain substances are astringent, such as the tannins in wine, tea, sloe, persimmon, and quince. After the ingestion of an astringent substance, the mouth is dried out due to its effect on a protein contained in saliva, called amylase. Acne treatments may contain astringent products in order to tighten skin pores. Astringent products also have a rapid effect on insect stings and small cuts.
