Alpinia Fruit Whole (Alpinia oxyphylla), known in Traditional Chinese Medicine as Yi Zhi Ren (益智仁), is the dried fruit of a subtropical ginger-related plant used to warm the kidneys and spleen, secure essence, and stop excessive urination or salivation. These small, reddish-brown fruits are aromatic and slightly pungent, making them a valued herb in formulas that address deficiency cold in the lower body and middle burner. Yi Zhi Ren is traditionally used for symptoms such as frequent urination, incontinence, spermatorrhea, or excessive drooling, especially when caused by spleen and kidney yang deficiency. It also helps improve appetite, reduce diarrhea, and warm the digestive system, particularly when there is internal cold with a lack of digestive fire. Because it is both astringent and warming, Alpinia fruit is often included in formulas aimed at tonifying without creating stagnation, making it suitable for long-term support in weak or elderly individuals. It pairs well with herbs like Rou Dou Kou (nutmeg), Shan Yao (Chinese yam), or Bu Gu Zhi (Psoralea). When decocted, Alpinia Fruit Whole yields a warm, spicy infusion with aromatic undertones that invigorate digestion and stabilize lower-body functions. Each batch of Alpinia Fruit Whole (Alpinia oxyphylla) is carefully harvested and dried to preserve its natural oils and potency. Whether used in kidney-tonifying formulas, digestive supports, or essence-securing blends, Yi Zhi Ren offers a gentle, warming path to restoring balance in cases of cold-type deficiency and leakage.
