A popular and highly prized herb in the East, ginseng is one of the oldest known medicinal plants. The English name ginseng is derived from the Chinese term 人参, which literally means “man root” due to the herb’s close resemblance to the human form. There are two common types of ginseng, namely Asian ginseng (Panax Ginseng) and American ginseng (Panax Quinquefolius).

In traditional Chinese medicine, Chinese and Korean ginsengs are thought to possess “heating” properties, which support the Yang energy in the body and help to improve blood circulation. American ginseng, on the other hand, has more “cooling” properties which promotes the Yin energy and calms the body.

Ginseng is a well-known adaptogen, which helps to increase the body’s resistance to stress and relieve physical and emotional fatigue. Ginseng is stimulating and yet restorative, improving alertness, ability to concentrate, stamina as well as strength. It also boosts metabolism and helps to normalize body systems, including blood glucose levels. According to Wikipedia, various studies found that American ginseng helps to regulate blood sugar levels in diabetic patients.

Since ancient times, ginseng has been used as an aphrodisiac. Modern studies on animals have also proven its ability to enhance libido and sexual performance. A study done by the University of Hong Kong has also found ginseng’s ability to inhibit the inflammatory gene CXCL-10, suggesting that this famed longevity root may have anti-inflammatory effects.

Caution: In traditional Chinese medicine, the use of ginseng is prohibited when one is down with an infection, as it’s believed the ginseng will strengthen the ‘forces of evil’ within the body. Ginseng should also not be taken at night if you’re suffering from sleeplessness because of its ability to enhance alertness. Ginseng should also be avoided if you have high blood pressure or cardiovascular disease.

Also known as brahmi, gotu kola carries a long reputation as a wound and brain enhancer in Ayurvedic textbooks. It’s widely taken to increase physical and mental energy levels, and improve memory and concentration. When combined with a meditation practice, gotu kola can also effectively reduce anxiety and enhance mental clarity.

A recent study done in India found that thirty-three participants who were given 500 mg of gotu kola extract twice daily for 60 days not only reported reduced occurrences of anxiety attacks, but also experienced lesser episodes of stress and depression.

Further, in one small study done on laboratory animals, scientists found that gotu kola may protect the brain against neurodegenerative disorders such as Parkinson’s disease.

Besides enhancing mental functions, gotu kola is also used in a wide variety of illnesses, ranging from healing of wounds and indigestion to respiratory congestion and dementia.

A study done by Chongqing Medical University found that an extract of gotu kola also exhibited anti-inflammatory properties and could protect against liver injury caused by diseases such as hepatitis.

In traditional Chinese medicine, in which it’s known as Luei Gong Gen, gotu kola is reputed to increase longevity. Legend has it that Chinese herbalist, Li Ching Yun, reportedly lived to the age of 256 partly by drinking a herbal formula containing gotu kola.

Caution: Gotu kola is generally well-tolerated by most people, but consuming high doses of the herb may induce headaches. Therefore, like most supplements, do not exceed the manufacture’s recommended dosage.
