What is Gotu Kola?
Gotu kola is a creeping, herbaceous plant that covers the ground with its green, fan-shaped leaves and thin stems. This tropical plant belongs to the Apiacea family, which also includes plants like carrots and parsley.
Gotu Kola prefers the moist, shady soil of river edges, rice paddies, and swampy areas. It can be found growing throughout tropical and subtropical Asian countries, Australia, and parts of Africa.1,2,3
Gotu kola has long been an important medicinal plant of Asia and is now becoming more popular in the West. It has traditionally been used to enhance cognition and support skin health, although it provides a wide variety of other benefits as well.
Modern scientific research has confirmed many of its traditional uses, and today, it is called upon to revitalize the brain, balance mood, support healthy skin, improve circulation, and balance blood sugar.
Note: Gotu kola is sometimes confused with the herb bacopa (Centella asiatica) since both herbs are sometimes referred to as brahmi depending on the information source or medicine tradition. While bacopa is a wonderful herb with some similar uses to gotu kola, the two should not be confused and are not the same plant.
Benefits of Gotu Kola and How It Works
Brain Revitalizer
Gotu kola is arguably most well known for its brain-supportive qualities. It has a long history of being used to enhance cognition and memory. Ayurveda, a traditional medicine system of India, has documented its beneficial effects on memory since ancient times.4
Gotu kola supports the brain through a variety of mechanisms, including balancing the central nervous system, promoting a primary calming neurotransmitter called GABA, combating oxidative stress, and restoring mitochondrial function.5
Its anti-inflammatory and antioxidant properties are mostly responsible for its ability to fight damaging oxidative stress, a common underlying factor in neurodegenerative diseases like Alzheimer’s and Parkinson’s.4
Gotu kola has also been shown to reduce glutamate-induced cognitive deficits and restore proper levels of antioxidants like glutathione.4
In a placebo-controlled, double-blind human clinical trial, improvements in mood and memory were experienced by healthy elderly subjects who received 750 mg of a gotu kola extract for two months. The authors note that the precise mechanism underlying these effects requires further investigation.6
Promotes Balanced Mood
In Eastern cultures, gotu kola has traditionally been used for its calming properties. In India, it is used to decrease anxiety. The extract has demonstrated the ability to modulate GABA, a naturally-occurring amino acid that has a relaxing effect on the brain and nervous system.1,7
In a 2010 human clinical trial, participants were given 500 mg of a gotu kola extract capsule twice daily for 60 days. At the end of the 60-day period, the participants reported a reduction in anxiety and depression symptoms, as well as an improvement in the perception of stress. The authors report that this may be due to gotu kola’s potential to regulate the HPA axis, an endocrine pathway that adapts and responds to stress.8
Supports Healthy Skin
In Asia, gotu kola has been used for hundreds of years to promote the healing of wounds and skin conditions like eczema.9
Asiaticoside, a compound found in gotu kola, can stimulate collagen and the formation of new blood vessels, which is essential in the wound-healing process. It can also balance inflammation, which promotes healthy scar formation.1
In an animal study, both oral and topical administration of a gotu kola extract had beneficial effects on wound healing. The extract was found to increase new cell growth and collagen formation at the wound site.10
Gotu kola is also used to improve blood flow to the skin, decrease cellulite, and reduce varicose and spider veins.3
Improved Circulation
Gotu kola has an affinity for connective tissue, especially the connective tissue that makes up vascular walls. It can strengthen weakened veins and improve circulation from the lower extremities back up to the heart.1
In a double-blind, placebo-controlled study, patients with venous insufficiency of the lower limbs were given gotu kola extract at 120 mg/day, 60mg/day, or a placebo. After two months, the gotu kola extract groups showed improvement in heaviness and edema in the lower limbs compared to the group who received the placebo.11
Blood Sugar Balance
In Tanzania and certain districts of India, gotu kola has traditionally been used to manage blood sugar. This usage is affirmed by modern scientific research that has demonstrated gotu kola’s ability to lower glucose levels.12
A 2014 study attributed this effect to the herb’s capacity to reduce glucose absorption throughout the GI tract. The study also found that consistent use of gotu kola reduced LDL cholesterol.12
Mild Antimicrobial
Although gotu kola may be better known for some of its other functions, this herb possesses mild antimicrobial activity that includes antibacterial and antiviral actions.16, 17
Both in vitro and animal studies have confirmed that gotu kola extract demonstrates antibacterial activity against H. pylori, a common bacteria that, in excess, can lead to infection and damage to the gastrointestinal tract.
Like many bacteria, H. pylori has developed some tolerance to antibiotics, making gut microbiome-balancing herbs like gotu kola even more valuable.16
History & Traditional Use
Gotu kola, or mandukparni in Sanskrit, has a long and rich history of use in the Ayurvedic tradition of medicine. Thousands of years ago, it was listed in Sushruta Samhita, an ancient Sanskrit text on medicine and surgery.1
In Ayurveda, gotu kola is considered a rasayana, a general tonic for increasing longevity. Brahma Rasayana is an important Ayurvedic formulation consisting of gotu kola alongside other herbs and fruits that are made into a paste and combined with warm milk. This comforting beverage is used as a brain tonic and to nourish the nervous system.2
Gotu kola is also an important medicinal herb in China and is sometimes called the “miracle elixir of life,” a flattering nickname in reference to Li Ching-Yun, a long-living herbalist who reportedly used gotu kola regularly.2
In Chinese folk medicine, the tea is used for tonsillitis, colds, jaundice, and more.3
How to Use and Dosing
Gotu kola is most often consumed as capsules or as a tincture. General dosing for standardized powdered extract capsules is 200-400 mg, one to two times a day, and 1-3 mL, one to two times daily for a tincture.
Gotu kola is also occasionally prepared as a tea. To do this, pour 1 cup of freshly boiled water over a teaspoon of the chopped and dried herb. Let infuse for a few minutes up to 15 minutes before straining. Enjoy up to three cups a day.
Beyond its more medicinal preparations, gotu kola is also utilized in a culinary setting. In many Asian countries, it is used as a salad green or juiced fresh. In Ayurvedic tradition, it is infused into ghee, a clarified butter.
To enhance gotu kola’s brain-supportive effects, it can be combined with bacopa, ginkgo, turmeric, ashwagandha, cat’s claw, or lion’s mane mushroom.
Interactions
Individuals taking medications to lower blood glucose (such as metformin) should be aware that gotu kola also helps to reduce blood glucose. in people with elevated blood sugar. However, it will not lower blood sugar in people with normal blood sugar levels as this herb is considered a normalizer rather than an effector. Blood sugar levels should be monitored and dosages adjusted to avoid hypoglycemia.
Always check with your health care practitioner before use if you are taking medications. For more general education on potential interactions between herbs and medications, check out Dr. Bill Rawls’ article: Is it Safe to Take Herbs with My Medications?
Precautions & Side effects
Gotu kola is generally well tolerated and has a low potential for side effects. Because the herb promotes blood flow and stimulates menses, it is best to consult your healthcare provider if using it during pregnancy.
