Functions and Benefits of Fineleaf Schizonepeta Spike

Traditional Chinese Medicine (TCM) shows that Fineleaf Schizonepeta Spike has the following health benefits.

Fineleaf Schizonepeta Spike can dispel Wind to relieve Exterior syndromes. TCM believes that External diseases such as colds or allergies can only invade the body if the external environment overwhelms our wei qi (卫气, immune system). In order to counteract this invasion, Fineleaf Schizonepeta Spike can induce sweating to expel the disease from the body and stop it from invading further. Hence, the herb can be used for exterior syndromes such as cold, fever, headache without sweating. 

Also, Fineleaf Schizonepeta Spike can alleviate itching and rashes caused by Wind pathogens. For example, the herb can be used for skin eruptions, measles, urticaria, stress rash and boils when they first erupt, especially if accompanied by chills and fever.

In addition, when charcoaled, Fineleaf Schizonepeta Spike can stop bleeding. It can be used for hematemesis, epistaxis, hematochezia, metrorrhagia and metrostaxis, or other kinds of bleeding syndromes.

Other than the above Schizonepeta benefits, modern studies also suggest that Fineleaf Schizonepeta Spike, when used to make a decoction, may help to enhance blood circulation and increase the secretion of sweat. This decoction also can help to inhibit the growth of harmful bacteria such as Staphylococcus Aureus, the leading cause of skin and soft tissue infections, and Diphtheria Bacilli, a bacteria that usually affects the mucous membranes of the nose and throat.

The herb also has strong anti-inflammatory effects on inflammation induced by acetic acid, as well as a clear anti-alexin effect.
