Tongkat ali is a proven treatment for erectile dysfunction
Mostly falseThe Claim
Tongkat ali is sold as a natural remedy that reliably improves erections, often positioned as a 'herbal Viagra'.
Origin
Its traditional reputation as an aphrodisiac and its association with testosterone are used in sexual-health marketing.
What Science Says
A meta-analysis of RCTs found only 2 eligible trials (139 participants) and no significant overall difference versus placebo on the IIEF-5 erectile function score (0.91; 95% CI −1.50 to 3.33). A modest improvement (2.15 points) appeared only in the subgroup with lower baseline scores, and the authors called for more efficacy trials.
Verdict
Mostly False
