• The main properties of astringent herbs are their tannins. In the past tannins were used to produce ink and preserve animal pelts, hence the name “tanning” leather.
• Tannins are usually found in the barks and roots of the plant, but can be found in the leaves. The plant uses tannins to protect it from parasites.
• Astringent herbs tighten and tone tissues, and shrink inflamed tissues. They can effect any part of the body but normally are used to effect the digestive, urinary, and circulatory systems.

Examples: Goldenseal, Pau d’ Arco, Red Raspberry, White oak Bark, White Willow Bark, Yarrow, Black Walnut, and Eyebright.

EW (#861-3)- Contains Bayberry, Eyebright, Goldenseal and Red Raspberry. This is considered an astringent formula for inflamed mucus membranes, especially the eyes. The herbs stimulate circulation to the eyes, shrink inflamed tissues, alleviate pain, and fight infection. EW is frequently used as an eyewash. This particular formula is also beneficial for sinus infections, or allergies associated with itchy, watery eyes. The eyewash is beneficial when allergens have irritated the eyes. Empty one capsule (or half capsule) into an empty teabag liner, and tie it into a little ball. Bring hot water almost to a boil and pour over the EW “tea bag” in a teacup. Let cool to warm temperature. Use an eyedropper to wash the eye several times a day. Keep eyewash covered and refrigerated between use. Run the eyedropper with the cold eyewash under hot water to warm it each time.
