walnut shell

Walnut shell refers to the hard outer covering of the walnut fruit. It is a natural product widely recognized in traditional medicine for its diverse therapeutic properties, including antioxidant, anti-inflammatory, antibacterial, and anti-parasitic effects. It contains various beneficial compounds such as tannins, steroids, acids, iodine, polyphenols, and flavonoids. Walnut shell is used in various forms, such as tinctures, decoctions, powders, and topical applications, and is also found in herbal supplements and nutraceuticals. It is employed to address a range of conditions including digestive issues, skin ailments, cardiovascular problems, diabetes, and to support overall wellness. In the specific context of dry eye treatment, walnut shell is utilized as a component in 'walnut shell glasses' for moxibustion, a traditional Chinese medicine technique. This method involves heating the walnut shell (often after soaking in medicinal liquids) to apply warmth and therapeutic effects to the eye area, aiming to improve dry eye symptoms and enhance tear film stability.
