A Chinese herbalist will be able to tell the state of your organs just by feeling your pulse and observing your ear. Just as you are not symetrical in the inside, the left and right radial pulse are not the same. They reflect different organs as well as the state of your blood and tissues.
In the science and the art that is Chinese herbal medicine, the beauty is in the formula. By using the whole herb, and not just a potent extract of one compound, many formulas are adaptogenic. That means, the same herb can be used for both low energy and stress. They simply "regulate" energy. If it is too high, they bring it down, if it is too low, they bring it up. Formulas are also specially designed where some herbs moderate or even eliminate the harsh side effects of the main herb. Beautiful!
