For Patients & Caregivers

Gotu kola has not been shown to treat or prevent cancer.

Gotu kola is a plant that contains many biologically active compounds. Although this botanical has been studied extensively in the laboratory, very few studies have been conducted in humans. Laboratory studies have found a range of effects including improved wound healing and anti-inflammatory effects. Studies in humans have suggested that gotu kola can decrease venous pressure in people with venous insufficiency and may be able to relieve anxiety.

  • To treat burns
    Laboratory data and few human studies suggest that gotu kola aids in wound healing.
  • To lower high blood pressure
    Several clinical trials show that gotu kola can reduce venous hypertension in patients with chronic venous insufficiency, but there is no evidence that this herb can treat typical (arterial) high blood pressure.
  • To treat psoriasis
    Laboratory experiments suggest that gotu kola can reduce inflammation, but human data are lacking.
  • For sedation
    One preliminary study in humans found that gotu kola can decrease the ”startle response.”
  • To treat chronic venous insufficiency
    Several clinical trials support this use.
  • To improve cognitive function
    Data from a clinical study supports this claim.
  • You are taking drugs that are substrates of CytochromeP450 2C9, CYP 2D6, CYP 3A4, and CYP2 C19enzymes (Gotu kola may increase the risk of side effects of these drugs).
  • Contact dermatitis
  • Liver toxicity
  • Reduced fertility in female mice
  • Gotu kola should not be confused with kolanut. Gotu kola does not contain any caffeine and has not been shown to have stimulant properties.
  • Depending on where gotu kola is grown, the content of active compounds in this herb can vary widely.

For Healthcare Professionals

Centella asiatica, Hydrocotyle asiatica

Gotu kola is an evergreen perennial plant that is prevalent in East Asia and many parts of South Africa. Extracts from the leaf and the whole plant are used for a variety of conditions including venous insufficiency, varicose veins, wound healing, scleroderma, and scars. In vitro and in vivo analyses indicate that gotu kola has neuroprotective (13) and chemopreventive (14) (19) properties, and also protects against cognitive impairment (20). Madecassoside, an active constituent, was shown effective against arthritis (5) and myocardial infarction (4).

Topical application of an asiaticoside extracted from gotu kola enhanced burn wound healing (6), and an herbal preparation containing gotu kola was shown to benefit those with chronic periodontitis (15). Supplementation with gotu kola improved cognitive function and mood in the elderly (7), alleviated generalized anxiety disorder (16) and may help wound healing in diabetic patients (22).
Data also show a reduction in lower extremity edema with gotu kola compared to placebo in patients with chronic venous insufficiency (1) (2) (3).

Gotu kola should not be confused with kolanut. Gotu kola does not contain any caffeine and has not been shown to have stimulant properties.

  • Burns
  • Cancer treatment
  • Circulatory disorders
  • Memory loss
  • Psoriasis
  • Scars
  • Sedation
  • Varicose veins

The triterpenoids are considered to be the active constituents in gotu kola. Asiaticoside, a triterpenoid, demonstrates anti-inflammatory effects by inhibiting  lipopolysaccharide (LPS)-induced fever and inflammatory response, including production of serum tumor necrosis factor (TNF)-alpha, interleukin (IL)-6 , prostaglandin E(2) (PGE(2), liver myeloperoxidase (MPO) activity, and expression of brain cyclooxygenase-2 (COX-2) protein (23). Asiaticoside also promotes wound healing by stimulating collagen and glycosaminoglycan synthesis, and angiogenesis (6).  Another study showed that a gotu kola extract may regulate stress-induced premature senescence (SIPS) by preventing repression of DNA replication and mitosis-related gene expression (24).

A water extract of gotu kola prevented the formation of intracellular beta-amyloid aggregates in a mouse model of Alzheimer’s disease with high amounts of beta-amyloid (25). There is also preliminary evidence that gotu kola might have sedative and analgesic properties (9).

  • Isothankuniside, a glycoside isolated from gotu kola, was shown to reduce fertility in mice (12).
  • Contact dermatitis (17) and hepatotoxicity (18) (26) have been reported following use of gotu kola.
  • Cytochrome P450 substrates: Gotu kola inhibits CYP 2C9, CYP 2D6, CYP 3A4 (21) and CYP 2C19 (27) in vitro and can affect the intracellular concentration of drugs metabolized by these enzymes.
