Massage the Neiguan, Shenmen, and Sanyinjiao acupuncture points, and press the points with your finger or a blunt-tipped pen for about ten strokes to see if the symptoms are relieved. If the symptoms persist, especially chest pain or stomach pain (sometimes stomach pain is a reflex pain caused by the heart), seek medical attention immediately. For prevention, people who often have chest congestion, palpitations and dizziness can drink American ginseng, schisandra and maitake, repeatedly taken with hot boiling water, before 4:00 pm, so as not to interfere with sleep. However, do not drink them when you have a cold.
