Because the cause of urticaria is not clear in medicine, it may be difficult to treat, so you go to see a western doctor, and many times the doctor will tell you that it can't be cured, and taking antiallergic drugs can only be controlled. I'm not a doctor, because I used to have urticaria. Chinese and western medicine have seen it countless times, and experts and authorities have seen it, but it can't be cured. Later, I saw someone recommended "Urticaria Dao Lang Clear" on the Internet, thinking that it would be no harm to go to the store to have a look, so I went into the store to see the evaluation of drugs by people who used them (Taobao has the function of buyer evaluation), and also read the posts made by people who used it in the exchange area of the store, but I still couldn't believe it. Herbs for external use can be washed well, because Chinese medicine says that urticaria is a physical problem, a blood problem, and it needs detoxification. Everyone knows that detoxification is not difficult for Chinese medicine, but oral Chinese medicine is not effective in treating urticaria. In the desperate situation (a dead horse is a living horse doctor) and considering that this medicine is an external Chinese medicine, it is more reassuring to cook it yourself. If it is prepared, I dare not use it, for fear that there are hormone drugs in it. From a security point of view, it is safe). At the seller's suggestion, I bought 10 days first (one course of treatment), and washed a lot in the first 4 or 5 days until 8 or 9. I think so, too. External washing may be absorbed by the skin more directly and effectively, so the effect will come faster. Having said that, why not go to see it yourself and consult it yourself? The seller is very nice (I also saw that the seller decided to consult on the Internet at that time, and you only need to communicate with the seller to know that others' comments on him are true). Well, besides, it is suspected of advertising. I am here to answer questions in order to help more patients with urticaria. I wish you get rid of urticaria as soon as possible!
