Introduction
It is commonly cultivated for viewing. The fruit tastes astringent and is boiled or soaked in sugar liquid for consumption. It is used as medicine to relieve hangover, remove phlegm, smooth the flow of gas, and stop dysentery. The peel remains smooth after drying and does not shrink, so it is called smooth-skinned papaya. The wood is hard and can be used as bed posts.
There is another species "papaya" native to South America. It was introduced to my country in the 17th century and has now become a popular fruit. It is also often referred to as "papaya" (see the entry "papaya"). Only the traditional Chinese "papaya" is described here.
