walnut extract

walnut extract (Juglans sp.) is traditionally used for soothing and antiitching action, as well as against sunburns and other superficial burns. Its fungistatic, anti-septic, and astringent properties can be beneficial in cases of acne and skin diseases. The extract is obtained either from the walnut leaf, which is said to be astringent and cleansing, or from the shell, which is considered astringent and emollient with some odor-masking activity. Tannin is a primary constituent of walnut extract.
