Source of validity: Traditional
Rating (out of 5): 2

Jujube (Ziziphus jujuba) has a long history of use in traditional medicine systems, particularly in Traditional Chinese Medicine (TCM) and other Asian practices, for supporting heart health and treating symptoms associated with "heart weakness." In TCM, jujube is often prescribed to "nourish the heart and calm the spirit," which typically refers to addressing symptoms such as palpitations, anxiety, insomnia, and general fatigue — collectively understood as manifestations of heart weakness or deficiency. Historical texts and herbal compendiums, such as the "Shennong Ben Cao Jing," note jujube’s use for strengthening qi (vital energy) and replenishing blood, both believed to be important for a healthy heart.

Modern scientific studies on jujube focus mainly on its antioxidant, anti-inflammatory, and anxiolytic effects, but robust clinical evidence specifically supporting its efficacy for heart disease, heart failure, or cardiac function is limited. Some animal studies suggest potential cardioprotective effects, such as reducing lipid peroxidation and improving lipid profiles, but these findings are preliminary. Therefore, while the use of jujube for heart weakness is well-rooted in traditional medicine, contemporary scientific validation remains modest. Its use is primarily justified by tradition, with a modest (2/5) evidence rating due to the lack of direct clinical trials and limited mechanistic data.
