As for the core medicinal materials for making belly button stickers, a secret recipe containing longan pulp, pepper and wormwood is popular at present, which comes from nan huaijin's "I said I could participate in the same appointment". According to the previous experience, the ratio of longan pulp, pepper and wormwood is 2: 1: 1, and the effect is better. Among them, longan pulp can nourish the heart and spleen, pepper can dehumidify and warm the spleen and stomach, and wormwood can regulate qi and blood and warm the uterus. These herbs can be bought directly in pharmacies. In the production process, the impurities in the pepper are first picked out, then the pepper and longan meat are put into a cooking machine to be broken, and then the moxa sticks are slowly added several times, and then stirred while adding, so that the adhered ones can be just kneaded into a ball. Finally, put the medicine into a medical adhesive tape and fix it on the navel for use before going to bed.
It is worth noting that the service time is about 12 hours, not as long as possible.
