 English Name: Prepared Fleeceflower Root
 Latin Name: Radix Polygoni Multiflori Preparata
 Property and Flavors: Warm or slightly warm in nature; bitter, sweet, and astringent in taste.

 Brief introduction: Radix Polygoni Multiflori Preparata is the root of Polygonum multiflorum processed with black bean juice. It is used to nourish Liver and Kidney Yin and tonify the Blood, primarily for conditions arising from Liver Blood deficiency and Kidney Essence deficiency—such as dizziness, tinnitus, soreness and weakness of the lower back and knees, and premature graying of hair. It is commonly known as Radix Polygoni Multiflori Preparata, Prepared Fleeceflower Root, or Zhì Hé Shǒu Wū.

 According to the English–Chinese Rare Chinese Materia Medica, raw Ho-Shou-Wu—that is, the dried root not processing with soybeans—is used to treat toxicosis (infections causing abscesses, subcutaneous swellings, sores, carbuncles, and eruptive diseases such as rubella), inflammation, constipation, and hyperlipidemia. Soybean-processed Ho-Shou-Wu is used as a tonic for Yin and blood, nourishing the hair, strengthening bones and muscles, and treating pale complexion, dizziness, tinnitus, premature graying of the hair, weakness of the lower back and knees, numbness of the extremities, metrorrhagia, metrostaxis, profuse leukorrhea, debility following protracted illness (e.g., malaria), and hyperlipidemia. Evaluations comparing raw and processed Ho-Shou-Wu indicate that the processed form possesses distinct pharmacological properties and exhibits the most pronounced effects on preserving immune system function. Processed Ho-Shou-Wu is currently the only form regularly exported from China. Over the past thousand years in China, processed Ho-Shou-Wu has been used to nourish the Liver and Kidneys, promote hair growth, and treat premature graying of the hair.

 The roots of Ho-Shou-Wu are reddish brown. The taste is starchy, astringent, and slightly bitter. The highest-quality roots are dense and firm. In Hong Kong, the highest-quality roots are sliced very thinly and carefully packaged to display the color, shape, and luster of the slices; ordinary-grade roots are sliced thicker and sold in bulk.
