The first weapon of a martial artist is his fist. The more power behind it, the stronger and more resilient the structure of the hand must be.
These ancient formulas work on two levels; the physical and energetic. Physically they help keep the skin soft, prevent bruising and callousing and help to prevent sprains before they occur. Energetically they increase circulation of both blood and chi. Increased blood circulation flushes damaged cells and increased chi circulation means that some acupuncture points are opened and others closed to increase the transfer of power.
a note for Martial Aritists;
Long ago, martial art masters in Kung Fu, Karate and Ta Kwon Do recognized the absolute need for a medicated herbal formula to protect the hands during intensive toughening exercises.
Preparations were developed which could speed the development of the hands while resisting unwanted side effects which cause delays in training and set the stage for further problems such as physical damage to the hand or energy blocks which interfere with the acupuncture meridian flow.
