You may be wondering why I sometimes tell you to just acupressure the hand, and sometimes specific points...There are different kinds of acupuncture/pressure...Some of them are
1. Sujok (Face) ...very minute needles are used for this
2. Palm (hand)...for this also minute needles are used
4. Auricular (Ear)
5. Foot (the famous Thai massage is based on this. simple pressure giving relief to many diseases)
These are based on the fact that the energy meridians end in the palm, foot, ear, head, face and the tongue for every human. Apart from these, the classical acupuncture deals in the 14 meridians identified in our body. Normally I give those meridian points in the tips. Kirilian photography shows these points as dots in our body (for those who want scientific proof!!!)
An important varma/acupuncture point below the nose just above the lips (DU 26 or GV 26 -Governing Vessel) is used to stop fainting. Whenever a person near you is about to faint, you can simply press (softly) this point or shake the point (left to right) to bring the patient into consciousness at the earliest. This can even be tried on your own. If you feel little giddy , press this point for getting back to normal soon.
Also useful in case of acute low back sprain. After gaining energy, the patient may be told to bend and rotate the waist. This point releases the stagnant energy (Qi - spelled as Chi in Chinese) at the farther point of the channel. Please see the attached picture for a clear idea of the point.
