In traditional Chinese medicine, Rehmannia glutinosa (Shu Di Huang, Prepared Rehmannia Root) is renowned for its effects of
nourishing blood and yin, replenishing essence and marrow. It effectively alleviates symptoms like blood deficiency-induced pale complexion, dizziness, irregular menstruation, and yin deficiency-caused night sweats, dry mouth, and weak waist and knees. From a modern research perspective, it contains bioactive components such as Rehmannia polysaccharides, catalpol, and Rehmannioside, which have immunomodulatory, antioxidant, and hematopoietic effects, helping to enhance the body’s resistance and regulate blood and yin deficiency.

【Storage Methods】
- Store in a
cool, dry, and well-ventilated place, away from direct sunlight and high humidity to prevent mold and deterioration. Due to its sticky texture, it’s prone to moisture absorption, so sealing is crucial. - Use airtight containers like glass jars or vacuum-sealed bags. Ensure the container is sealed tightly after each use to avoid moisture absorption and insect infestation.
- Regularly check for signs of spoilage, such as mold, stickiness, or unusual odor. Discard any spoiled Rehmannia glutinosa immediately.
