Abalone, known as "Shi Jue Ming" (石决明) in Traditional Chinese Medicine (TCM), is primarily used for its purported benefits in calming the liver, improving vision, and treating conditions related to excessive heat or wind, such as headaches, dizziness, and eye disorders. There is a traditional belief in some East Asian medical systems that abalone shell may have a general tonifying effect, but its use specifically for "heart weakness" is only weakly supported by historical texts. While TCM sometimes associates the heart with mental and emotional well-being and may use abalone in formulas intended to calm the spirit or subdue yang, direct references to abalone treating "heart weakness" (a term that can be ambiguous and covers a range of symptoms in traditional and modern medical contexts) are sparse. There is no robust body of clinical or pharmacological evidence to support abalone’s effectiveness for cardiovascular conditions in modern medical literature. Thus, its use for heart weakness is primarily based on tradition, and even within tradition, the association is limited and indirect. No high-quality scientific validation exists for this application, and any use for heart-related conditions should be approached with caution and under professional guidance.
