Rating (out of 5): 3

Lesser Galangal (Alpinia officinarum) has a long history of use in traditional medicine systems, particularly in Traditional Chinese Medicine (TCM) and Ayurveda, for stimulating appetite and addressing digestive complaints such as "deficient appetite." In TCM, it is known as "gao liang jiang" and is commonly prescribed to "warm the middle," expel cold, and improve appetite and digestion by invigorating the spleen and stomach. Traditional texts often mention its use for symptoms like poor appetite, abdominal pain, and bloating, which are interpreted as manifestations of digestive deficiency or coldness affecting the gastrointestinal tract. While there is a robust tradition of using Lesser Galangal for these purposes, scientific studies specifically confirming its efficacy in improving appetite are limited. Some phytochemical investigations have identified bioactive compounds such as galangin, flavonoids, and essential oils, which may have mild stimulatory effects on the digestive system, including promoting gastric secretions. However, the evidence from controlled clinical trials remains insufficient. Most of the support for its appetite-stimulating effect is grounded in centuries of empirical use and historical texts rather than modern pharmacological validation. In summary, Lesser Galangal’s use for appetite deficiency is primarily justified by traditional medical systems, with moderate evidence based on longstanding practice and some preliminary pharmacological insights, but limited direct scientific validation.
