The ST 10 Point
The stomach 10 point is located directly over part of the carotid artery and a branch of the vagus nerve. Striking this area can cause increased parasympathetic stimulation of the heart via vagus nerve stimulation. In a susceptible individual, this can lead to a loss of consciousness at the very least and cardiac arrest at the very worst. Striking this point can also cause damage to the carotid artery leading to a stroke. There are multiple case reports where blunt trauma to this area resulted in carotid artery damage and neurological deficits. This point is especially effective when combined with the stomach 9 point. However, this combination is more likely to cause serious carotid artery damage leading to stroke and/or death.
