Gotu Cola
Also known as: Centella asiatica, Gotu kola, Asiatic pennywort, Brahmi
Overview
Centella asiatica, commonly known as Gotu kola, is a plant native to the tropical regions of Asia and Africa. It has a long history of use in traditional medicine, particularly for wound healing, skin conditions, and cognitive enhancement. The plant contains triterpenoids, which are believed to be responsible for its biological effects. While research on Gotu kola is still evolving, some studies suggest potential benefits for cognitive function, particularly in individuals with cognitive impairments. It is available in various forms, including capsules and extracts. The quality of available evidence varies, and more research is needed to fully understand its effects and optimal usage.
Benefits
Some studies suggest that Gotu kola may improve working memory and delayed recall memory, especially in individuals with cognitive impairments post-stroke. Research indicates that supplementation may lead to cognitive benefits within several weeks. Additionally, Gotu kola has potential benefits for mood and stress reduction, although the evidence is less robust in these areas. The effect sizes and clinical significance of these benefits require further quantification through additional research. Overall, Gotu kola shows promise as a cognitive enhancer, particularly for those with existing cognitive deficits.
How it works
Gotu kola is believed to enhance neuroprotection and improve blood flow to the brain. Its triterpenoids may influence antioxidant pathways and neurotrophic factors, contributing to its cognitive effects. The exact mechanisms of action are still under investigation, but it is thought to interact with the nervous system to improve cognitive function. Limited data is available on the absorption and bioavailability of Gotu kola's active compounds, which may affect its efficacy.
Side effects
Gotu kola is generally considered safe when used appropriately, but it can cause side effects in some individuals. Common side effects include dizziness, headache, abdominal pain, nausea, skin disorders, and drowsiness. Uncommon side effects may include elevated liver enzymes, although this is not consistently significant. Due to its potential effects on blood sugar and clotting, Gotu kola may interact with blood thinners and diabetes medications. It is contraindicated in pregnancy and breastfeeding due to insufficient safety data. Caution is advised for individuals with liver conditions or those taking medications that affect liver function.
Dosage
The minimum effective dose of Gotu kola is not well-established, but typical dosages range from 500 mg to 1000 mg per day. Studies investigating cognitive benefits have used dosages of 750 mg to 1000 mg per day. The maximum safe dose is not clearly defined, and high doses may increase the risk of side effects. There are no specific timing recommendations for Gotu kola supplementation. It is commonly available in capsule or extract form. Bioavailability may vary based on the extraction method and formulation. No specific cofactors are required for its use.
