What is Rhizoma Belamcandae (She Gan)?

Rhizoma Belamcandae (she gan, 射干)  is the rhizome of the plant Belamcanda chinesis, also known as the Leopard Lily Plant. It is a perennial herbaceous plant native to East Asia, particularly China and Japan. 

In China, Belamcanda chinesis is often found in provinces such as Hubei, Henan, Jiangsu and Anhui. The rhizomes are usually dug out in early spring or late autumn, when the plant just started to sprout or when the leaves start to wither.

In Traditional Chinese Medicine (TCM), She Gan falls under the category of ‘Herbs that clear Heat and relieve toxicity’. Such herbs are used to clear inflammatory and infectious conditions, referred to as ‘Internal Heat’ in TCM. Such herbs usually have both antibacterial and antiviral properties.

Cold in nature, She Gan can help individuals with too much Heat in their body, such as those experiencing a Yang Excess or a Yin Deficiency, to restore a harmonious yin-yang balance. Bitter in taste, She Gan has a cleansing action on the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements. In particular, the herb targets the Lungs.

Functions and Benefits of Rhizoma Belamcandae (She Gan)

Traditional Chinese Medicine (TCM) shows that She Gan has the following health benefits.

She Gan can clear Heat and remove toxicity, which makes it a great herb to alleviate sore throat, relieve swelling, address bad breath, clear Heat in Lungs and dispel phlegm. In particular, She Gan is very effective in the treatment of Heat-toxicity syndromes manifested as swollen and sore throat due to turbid-phlegm stagnation.

For sore throats caused by excessive Heat-toxicity, it can be combined with other toxicity-removing and sore throat-alleviating herbs to enhance its effects. For sore throats with hoarse voices caused by Wind-Heat invasion of the Lungs, She Gan can be combined with Wind-Heat-dispersing herbs to enhance its effectiveness.  In addition, She Gan can be used orally or topically to treat syndromes of Heat-toxicity such as sores, abscesses and mumps.

As She Gan can clear Heat in the Lungs, direct qi downwards and dispel phlegm, it can relieve cough and asthma, especially those caused by Stagnation of excessive phlegm and saliva, as well as wheezing due to retained phlegm in the throat. This herb is also indicated for cough and asthma caused by Cold-Phlegm and cold drinks, but it must be used together with other herbs that can warm the Lungs, resolve Phlegm, relieve cough and asthma.

She Gan’s ability to activate one’s blood and eliminate phlegm also makes it a commonly used herb in the treatment of amenorrhea, mass malarial nodule, scrofula and subcutaneous nodule.
