Gotu kola is a low growing plant which likes wet soil
Originally published on Herbal Medicine from Your Garden
Gotu kola is the Sinhalese name for Centella asiatica (syn. Hydrocotyle asiatica, H. cordifolia, H. erecta, H. repanda and Trisanthus cochinchinensis), also called Asiatic pennywort, brahmi, centella, Indian pennywort, ji xue cao, kodokan, marsh pennywort, pennyweed, sheeprot and thankuni amongst many other names worldwide. It is not related to kola nut or to Bacopa monnieri (also called brahmi).
Gotu kola is a low growing (to 8″, 20cm tall) but wide spreading (up to 3′, 1m) evergreen perennial which will grow in any moist or wet soil, so long as it’s not in full shade. It is native across Asia, Africa, South America, the Pacific islands and Queensland, Australia and is naturalized in Norway, strangely. The reason this is odd is that it will not tolerate frost, but in areas with harsh winters it could be grown in pots under cover during the cold season, if fresh supplies are required all year round. In warmer areas, it can be used as groundcover in moist soil.
Seed can be sown under cover in Spring and grown on indoors for the first Winter, planting out in their permanent position the following Spring after the last frost date. Divide some plants in the Fall and bring the divisions indoors to ensure continued supply even if your outdoor crop is killed by the weather.
You should be able to arrange to have fresh leaves available all year round, and they can be harvested at any time. You can also dry them, but they quickly lose their efficacy so it’s best only to do so when you know you will be using them in a short time – to take on vacation with you, for example. You can also buy in powdered form.
This plant is used in many recipes across its range, including sambola, brahmi tambli (scroll down), Acehnese pennywort salad (near the end) and green Thai tea drink.
It is a traditional herb in Ayurvedic, Chinese and African medicine. However, there are some precautions that you should be aware of before using it:Not suitable for use by children, diabetics, cancer patients (even in remission), or anyone with liver disease. Do not use gotu kola if you’re taking any of the following: green tea, astragalus, ginkgo, valerian, statins and other cholesterol lowering drugs, diuretics, sedatives or any drug (whether conventional or herb-derived) that affects the liver.
The standard recommendations for gotu kola are: Do not use for more than 6 weeks at a time, and then leave at least two weeks before taking it again. Having said all that, it seems strange that all these restrictions are recommended when it seems to be a regular part of the diet in Sri Lanka, Indonesia, Malaysia, Thailand, Vietnam and Bangladesh. It is also an important healing herb across Asia including India and China.
A standard infusion can be made in the usual way using 3 handfuls of fresh or 15g dried leaves or powder to 500ml (2 US cups, 8 fl oz) boiling water, brewed for 10-15 minutes and then strained.
A standard extract (should contain 40% asiaticoside, 29-30% asiatic acid, 29-30% madecassic acid, and 1-2% madecassoside) is available in some health outlets. You can also buy or prepare a tincture (full instructions for making tinctures and other types of remedy can be found in my Kindle ebook Home Remedies and How to Make Them which is available for only 99p in your local Amazon store).
Dosage (standard extract): scleroderma 20mg 2 or 3 times a day, venous insufficiency 30-40mg 3 times a day; (standard infusion): 250ml (1 US cup, 4 fl oz) a day, which may be split into 2 or 3 doses;(tincture): 30-60 drops 3 times a day.
Do not exceed the stated dose. Use half the standard dosage for the elderly.
Gotu kola is a very valuable herb with many healing properties. As well as fighting bacterial and viral infections, it also works against inflammation, rheumatic problems, high blood pressure and ulceration. On the non-physical side, it’s also helpful in improving memory, preventing panic attacks, reducing nervous tension and as a sedative. Recent research shows that when applied topically it stimulates production of collagen and reduces scarring, inflammatory reaction and myofibroblast production – which explains both its reputation as a wound healer and its use in cosmetic masks and creams reputed to increase collagen and firm the skin.
It is a traditional tonic and is used for diarrhea and other digestive problems, as a diuretic and detoxifier, to reduce inflammation and promote healing and also to balance the emotions and improve memory and concentration. Although normally used externally for wounds and skin conditions, it is also taken to speed up the body’s natural repair mechanisms. Other conditions for which gotu kola is used include leprosy, malaria, scleroderma, venereal disease, varicose veins and venous insufficiency. You can use any of the methods described above to treat them.
Externally a cold standard infusion or a poultice of leaves is used for minor burns, psoriasis and other skin conditions, as a wound herb, for hemorrhoids (piles), rheumatic pain and to reduce stretch marks and scarring.
In India gotu kola is mainly used to strengthen memory and nervous function. In Thailand it is used as an opium detox.
Avoid using artificial treatments, including pesticides and fertilizers, on your gotu kola, Plants take up chemicals they come in contact with and it’s not so nice to ingest them with your herbal remedies!
