Gotu kola (Centella asiatica) has a history of use in traditional medicine for improving circulation and supporting vein health. Scientifically, several studies have investigated gotu kola’s effects on venous insufficiency, which is related to spider veins and varicose veins. Gotu kola contains compounds known as triterpenoids (including asiaticoside, madecassoside, and asiatic acid) that are believed to strengthen blood vessel walls, improve microcirculation, and reduce leakage from veins.

Clinical trials, particularly in Europe and Asia, have shown that gotu kola extracts can reduce symptoms such as swelling, edema, and the sensation of heaviness in the legs in people with chronic venous insufficiency. For example, a review published in Angiology (2001) summarized several studies demonstrating improvements in microcirculatory parameters and reductions in edema among patients taking gotu kola extracts.

While most research focuses on chronic venous insufficiency and varicose veins, these conditions share similar pathophysiological mechanisms with spider veins (telangiectasias). However, direct evidence for gotu kola specifically treating or reducing the appearance of spider veins is limited; most benefits are extrapolated from broader vascular studies. Adverse effects are rare but can include headache and gastrointestinal discomfort.

In summary, there is scientific evidence supporting the use of gotu kola for venous health, with moderate evidence for its potential in managing symptoms related to spider veins, though direct clinical trials on spider veins themselves are lacking.
