Gotu Kola or "Centella asiatica" has been used in herbalism for hundreds of years to help with multiple ailments. It's most popularly used through the Ayurvedic practice. It's been used for thousands of years in India, China, and Indonesia because it is native to Asia. In Chinese culture it's even been referred to as the "fountain of life" because of all it's healing properties. It's been known to help heal wounds and even symptoms of psoriasis. It's also helpful if you have anxiety! If you are pregnant we recommend avoiding Gotu Kola because it can be teratogenic.

We encourage you to do your research before ingesting any herb. This is especially true if you are taking any medications, as many herbs interact with specific types of medications (St. Johns Wort and Antidepressants for example, causes serotonin syndrome, which can be fatal). Always consult your doctor before trying to treat, diagnose, or cure any medical condition, as they know what is best specifically for you.
