1, taboo crowd: Due to the cold nature of Guiling Ointment, people with weak spleen and stomach, loss of appetite and loose stools should not eat it. Tortoise shell can excite the uterus, which may lead to miscarriage, which is not suitable for pregnant women. In case of abdominal pain, no appetite, diarrhea, etc., you should stop using it immediately.

2. Taboo collocation:

(1) Guiling Ointment should not be eaten with cold and cool foods, so as not to aggravate the cold and cold qi in the body. In the long run, it is not conducive to the health of the spleen and stomach, and even worse, it is prone to abdominal cold pain and diarrhea. But for some healthy people, occasional and small amounts of eating together will not cause any discomfort.

(2) When taking warm drugs, it is best to avoid eating turtle paste, such as leek seeds, astragalus, pilose antler, epimedium, angelica and so on, because cold turtle paste may affect the nourishing effect of such drugs. However, this is not absolute. For example, many guiling ointments sold in the market are actually very weak in medicinal properties, and occasionally eating a little guiling ointment when taking medicine will not have any great influence.
