Half-minute Yankang spray original half-minute rhinitis Kangtai spray

It is true that within half a minute after nasal spray, the nose becomes unobstructed. The effect is very good and the price is cheap. A bottle costs more than ten yuan, and each bottle can be used for about one month. The instructions say that the ingredients of the medicine are composed of several Chinese herbal medicines, but I don't understand how many Chinese herbal medicines can produce such rapid effects. Whether it contains drugs that constrict the blood vessels of nasal mucosa is doubtful, and there is no evidence. If it contains drugs that constrict the blood vessels of nasal mucosa, long-term application may cause drug-induced rhinitis, which will be more difficult to treat. I really hope that the manufacturer of this medicine can give a real explanation. Let patients feel more at ease when using it.
