Gotu kola tea, also known as centella asiatica, is a plant traditionally used in traditional Chinese and Ayurvedic medicine. It is native to the wetlands of Southeast Asia and has been consumed as a juice, tea, or supplement for thousands of years. Gotu kola has been used for various purposes, including promoting mental health, improving circulation, and reducing inflammation.
Health Benefits
Enhanced cognitive function
Some early research suggests that gotu kola may enhance memory and overall cognitive function, which means it may have potential in treating Alzheimer’s disease. A 2016 study compared the effects of gotu kola extract and folic acid in improving cognitive abilities after a stroke. Both gotu kola and folic acid equally benefited participants, while gotu kola was more effective in improving memory.
Reduced anxiety
Some studies show that gotu kola may have a relaxing or anti-anxiety effect. In a 2016 study, researchers found that gotu kola reduced anxiety-induced behavior in mice that were sleep-deprived for 72 hours. While this research is still preliminary, it shows some promise in relieving stress and anxiety. In another study on humans, researchers found that gotu kola reduced the startle response in participants, which is often associated with anxiety.
Treatment for varicose veins
Several studies show that gotu kola can be used as a treatment for varicose veins and venous insufficiency. Participants who took a gotu kola supplement for eight weeks showed improvements in the health of their veins, including reduced inflammation and pain. Another study suggested that gotu kola supplements improved function of the veins in participants with diabetic microangiopathy, a condition that affects people with diabetes.
Side Effects and Precautions
Side effects
Gotu kola is generally well tolerated, but some common side effects of the herb include: drowsiness, nausea, headaches, dizziness, diarrhea, and skin irritation.
Precautions
Gotu kola should only be taken for two to six weeks at a time. Be sure to take a two week break before resuming use. If you begin experiencing any unusual or prolonged side effects, discontinue use and see your doctor.
Interactions with medication
Gotu kola could potentially interact with prescription or over-the-counter medications. It could amplify the effects of alcohol and sedative medications. Always consult your doctor before using gotu kola if you are taking any medications.
Conclusion
Gotu kola tea has been used for thousands of years in Ayurveda for its various health benefits. While there is some evidence to support its use for improved cognitive function and reduced anxiety, further research is needed in many areas before it can be widely recommended. Gotu kola tea is generally considered safe to consume when obtained from reliable sources, but careful dosing can help limit the risks. If you have any health conditions, especially liver disease, are pregnant, breastfeeding, or have a scheduled surgery, it is important to consult with your doctor before using gotu kola.
