Product Description
According to Chinese medicine, our qi and blood flow can be affected by invasion of energies from the external environment. These energies are wind, cold, dampness, heat, dryness, and summerheat. As mentioned above, one of the five functions of qi is to protect the body from invasion by these environmental energies. If the defensive qi is weak, environmental energy(s) can invade the body, settling into the channels, and block the flow of qi and blood in those channels. According to some Chinese doctors, such invasion by external energies can only occur if the defensive qi is deficient.
Invasion by these kinds of external energy usually involves at least two kinds of environmental energy. In other words, they do not usually invade the body singly but rather in pairs or triplets. For instance, wind often combines with heat, cold, and/or dampness. When these energies invade the upper body, we typically come down with a cold or flu. But when they invade the low back, we may get acute low back pain.
