A slight tremor is probably a sign of mental stress and physical decline. Japanese medical experts found in a survey that more than 70% people didn't realize it in the early stage of tremor, and when they found it, it was often too late. I suggest you adjust your schedule as soon as possible, don't stay up late, and eat reasonably, otherwise you will soon face the danger of neurasthenia!
Purple tongue: when the blood contains a lot of waste and the water supply in the body is insufficient, the oxygen-deficient blood and oxygen-containing blood will be mixed together, making the blood vessels turn purple. If the tongue turns purple, you will feel stiff shoulders and backache, which only shows that there are too many toxins deposited in your body! You might as well stick to a light diet for a week, do a sauna and keep regular light aerobic exercise, and the toxins will be discharged soon.
Too thick tongue coating: the tongue coating on the tongue is as easy to be scraped off as tofu residue, which may be caused by gastrointestinal dysfunction or overeating. If this tongue coating persists, you'd better go to the gastroenterology department and ask the doctor to help you reduce stomach fire.
Too thin tongue coating: the tongue coating falls off inexplicably and the color of the tongue surface is uneven, which is called "map tongue" in medicine. Korean medical experts pointed out that people with allergies are most likely to have this situation, especially in spring and autumn. The appearance of "map tongue" shows that your resistance is declining. It is recommended that you stay away from allergens such as pollen, seafood and small insects during this time to avoid being "caught".
Yellowing of tongue coating: Yellowing of tongue coating is probably a signal of cold virus invasion! Be sure to keep warm, eat more warm food such as pumpkin and beef, and soak a cup of hot milk before going to bed at night. A protein membrane can be formed in the stomach to prevent bacteria from invading.
