Where can I buy Kung Fu Pear Laiyang Pure Pear Paste? I heard that this thing is very effective in treating cough.

Rosa roxburghii paste, also known as Laiyang pear paste, is relatively rare and expensive. It is made of Laiyang pear, which is widely known by local people. Different from other pear creams, it is mushy (similar to honey). Generally, Laiyang pear sauce will not add anything else, because Laiyang pear itself contains natural protocatechuic acid that other pears do not have, which is why Laiyang pear is famous at home and abroad.

I know a company that makes authentic Laiyang Rosa roxburghii paste, called Hong Jie Yili. Pear cream is good, but it's also quite expensive. Eating pear cream often is better for the lungs and pharynx. People who smoke regularly eat well, and eating without smoking is also a good choice to fight smog.
