of which asiaticoside
Also known as: Asiaticoside, Centella asiatica extract, Gotu kola extract, Pentacyclic triterpenoid saponin
Overview
Asiaticoside is a bioactive compound derived from the plant *Centella asiatica*, commonly known as Gotu Kola. It has a long history in traditional medicine, particularly in Asian cultures, where it is valued for its neuroprotective, anti-inflammatory, and wound-healing properties. The compound is classified as a triterpenoid saponin and is utilized in various herbal supplements. Current research highlights its potential benefits in modulating gut microbiota and influencing neurotransmitter levels, especially in the context of depression. While studies illustrate promising effects, they primarily involve animal models, necessitating further clinical trials to validate its safety and efficacy in humans.
Benefits
Research indicates that asiaticoside may improve depression-like behavior through mechanisms that involve the modulation of gut microbiota and an increase in serotonin levels. Studies on animal models, particularly mice subjected to chronic unpredictable mild stress (CUMS), demonstrate notable efficacy, pointing towards its potential role as an antidepressant. Although there are indications of secondary benefits, such as anti-inflammatory and neuroprotective effects, these have been less thoroughly researched in humans. Overall, while the evidence is compelling from preclinical studies, the clinical significance and application require further exploration to confirm effectiveness in human populations.
How it works
Asiaticoside influences the microbiota-gut-brain axis, altering gut microbiota composition and promoting short-chain fatty acid production. This modulation affects the central nervous system by regulating neurotransmitter levels such as serotonin, thus impacting mood and cognitive functions. It is also believed to enhance the expression of neurotrophic factors like BDNF and receptor activity related to serotonin (5-HT1A), although its high molecular weight limits its absorption and bioavailability.
Side effects
While asiaticoside is generally deemed safe based on traditional uses, comprehensive data on adverse effects in humans are sparse. Common side effects have not been well-documented, and there is limited information regarding rare or uncommon side effects. Since the safety of asiaticoside during pregnancy and lactation has not been established, caution is prudent in these populations. Potential drug interactions have not been rigorously studied, and it is advisable for individuals with severe health conditions or those taking other medications to consult healthcare professionals before use. Overall, the lack of extensive safety profiling raises the need for caution and further research.
Dosage
Currently, the effective dosage of asiaticoside for humans is not firmly established. Animal studies suggest a range of 10-40 mg/kg, but specific recommendations for humans remain to be defined. Due to its poor absorption linked to high molecular weight, optimal timing, and necessary co-factors for absorption have not been explored. As a herbal extract, it is advisable to follow guidance from healthcare professionals regarding its use and to monitor for any potential adverse effects during consumption.
