Arjunic Acid is a triterpenoid compound isolated from the bark of the Terminalia arjuna tree, a plant widely used in traditional Ayurvedic medicine. The use of Arjunic Acid and Terminalia arjuna extracts for cardiovascular health, including lipid regulation, is supported by both traditional use and a small but growing body of scientific research. Several preclinical studies and a limited number of human clinical trials have investigated the lipid-lowering effects of Terminalia arjuna bark extract, which contains Arjunic Acid as one of its active phytochemicals. Some studies report a modest reduction in serum triglycerides and total cholesterol, likely due to antioxidant, anti-inflammatory, and potential lipid-lowering mechanisms of its compounds, including Arjunic Acid.

However, direct evidence for Arjunic Acid itself (as an isolated compound) in the management of high triglycerides is limited, with most research focusing on whole bark extracts rather than the pure acid. The available clinical trials are generally small, short-term, and often use combination herbal preparations. Therefore, while preliminary data suggest a possible benefit, the strength of the evidence is low to moderate (hence a rating of 2), and more rigorous, large-scale human studies are needed to establish efficacy and safety. Until then, its use for high triglycerides is best considered as adjunctive and based more on early evidence than on high-quality clinical validation.
