What is the correct way to consume Polygonum multiflorum (He Shou Wu)?

The correct ways to consume Polygonum multiflorum include direct decoction, steeping as tea, or combining with other medicinal herbs to prepare soups or stews; the specific method should be selected according to individual constitution and needs. Raw Polygonum multiflorum can help lubricate the intestines, relieve constipation, and detoxify, whereas processed Polygonum multiflorum (after炮制—pao zhi processing) is more suitable for nourishing the liver and kidneys, enriching essence and blood, and promoting black hair and beauty. When preparing by decoction, an appropriate amount of Polygonum multiflorum can be sliced and boiled in water to make a medicinal liquid for consumption. For tea preparation, the herb can be sliced thinly or processed tea bags can be used, then steeped in hot water. Effects may be enhanced when combined with ingredients such as Lycium barbarum (goji berries) and Ziziphus jujuba (red dates). Different consumption methods may have varying effects on the body, so blind usage should be avoided.

To ensure safety, it is best to consult a qualified physician before consuming Polygonum multiflorum, especially for individuals with chronic diseases or those currently taking medications. Long-term and excessive consumption of raw Polygonum multiflorum may cause liver damage; therefore, processed Polygonum multiflorum is recommended. Additionally, the daily dosage should be kept within a reasonable range, and the exact dosage should follow the physician's instructions. Moreover, it is important to monitor physical reactions promptly. If discomfort symptoms such as abdominal pain or skin allergies occur, consumption should be stopped immediately and medical attention sought.
