Gotu Kola Leaf And Stem Extract
Also known as: Gotu Kola, Asiatic Pennywort, Centella asiatica
Overview
Gotu kola (*Centella asiatica*) is a hydrophilic perennial herb native to Asia, widely recognized in traditional medicine systems like Ayurveda and Traditional Chinese Medicine. The leaves and stems of the plant are rich in bioactive compounds, primarily triterpenoids, which are believed to provide a range of benefits. Commonly utilized for cognitive enhancement, wound healing, and as a brain tonic, Gotu kola's therapeutic potential is supported by some clinical studies, although the overall body of evidence remains moderate and varied in quality. The extract is often available in powder or capsule form, and despite its traditional use, systematic reviews supporting its efficacy are limited.
Benefits
Research indicates that Gotu kola may support wound healing and improve circulation, presenting small to moderate effect sizes. Some studies highlight its potential ability to enhance cognition, although results in human trials are inconsistent. Benefits may be more evident in individuals with mild cognitive impairment or those seeking improved circulation. A review of key studies reveals that while findings in animal models are promising, further robust clinical trials are necessary to validate these benefits fully and establish guidelines for use.
How it works
The mechanism of action of Gotu kola is primarily attributed to its antioxidant and anti-inflammatory properties. Triterpenoids like asiaticoside and madecassoside contribute to neuroprotection and may enhance cognitive functions by possibly interacting with serotonin receptors. This could influence mood and cognition, while also improving blood flow through the circulatory system, positively impacting various body systems.
Side effects
Gotu kola is generally considered safe for most individuals; however, some may experience gastrointestinal upset, especially at higher dosages. Allergic reactions are uncommon, with no rare adverse effects thoroughly documented. Users should exercise caution when taking blood thinners due to potential interactions that may enhance bleeding risk. Contraindications include pregnancy and breastfeeding, due to insufficient safety data in these populations. Caution is also advised for individuals with diabetes, as Gotu kola may affect blood glucose levels.
Dosage
The optimal dosage range for Gotu kola extract typically falls between 300-600 mg per day, though the minimum effective dose is not well established. There are no strict timing recommendations for administration. Oral capsules or tablets are the most common forms, with bioavailability potentially varying by formulation. Maximum safe dosages have not been clearly defined in the current literature, emphasizing the need for caution and gradual dosage adjustments.
