Gotu kola, or Centella asiatica, is a plant traditionally used in Chinese and Indonesian medicine. Known as the “herb of longevity,” this plant is indigenous to the wetlands of Southeast Asia. Gotu kola is celebrated for its anti-inflammatory benefits, as well as its potential to promote overall mental health.  

• A recent study published in the Indian Journal of Physiology and Pharmacology found that Gotu Kola has a significant effect on cognitive abilities, including improved alertness, concentration, and mental focus. The results of this randomized, double-blind, placebo-controlled trial indicated that those who took Gotu Kola for two months showed greatly improved cognitive performance compared to those in the placebo group.

• A study published in the Journal of Ethnopharmacology found that Gotu Kola was able to reduce mental fatigue and improve alertness in healthy volunteers who took it over a period of four weeks. The positive effects on mental focus, concentration, and memory were most pronounced within the first two weeks of taking the supplement.

• A study published in Evidence-Based Complementary and Alternative Medicine found that Gotu Kola may help to improve mental focus and concentration, possibly due to its ability to inhibit the activity of an enzyme associated with cognitive decline. The researchers concluded that it could be a useful natural supplement for those looking to improve mental performance.

• A study published in the journal Pharmacognosy Research found that taking Gotu Kola for four weeks led to significant improvements in participants’ attention, working memory, and executive functioning compared to those who took a placebo.

• Finally, a study published in Phytomedicine found that Gotu Kola was able to improve the mental function of elderly people suffering from memory loss. The researchers concluded that it may be a promising natural supplement for those looking to maintain their cognitive abilities in old age.

Overall, Gotu Kola appears to have many potential benefits for cognitive performance and mental focus, making it a great natural supplement to consider for those looking to improve their mental performance.
