Does Junbi Shahong Cao Snoring Capsule sell in Hainan? What's the effect?

The effect of this medicine is ok. I bought it for my family, and it's almost the same now. I have been snoring for more than ten years, and I have used more than one course of treatment. They are sold in Haikou. I bought it for the first time at Yuananlong Pharmacy next to Wanghai International Hotel on Haixiu East Road. Later, I called their Haikou number (0898-65323089) and they sent it to Sanya for free.
