For example, the well-known Sydney cream on the market includes Dong Yun, Enjitang, Yibeikang and Heniantang. Personally, I prefer Yi Bei Kang's bergamot Sydney cream, because it contains bergamot, a traditional Chinese medicine that Sydney cream doesn't have in the market. Bergamot not only has the effect of moistening the lungs, but also has the effect of relieving stomach pain and adjuvant treatment of nausea and vomiting. My father often coughs because of smoking. I bought him a bottle to drink before, and his cough has improved a lot. The effect is very good. I suggest asking the Lord to find out.
