Mangosteen peel sold at VND100,000

Mangosteen is a fruit mostly grown in the south and favored by people throughout the country. In general, people throw mangosteen peels away as they think they are useless. But in fact, they are very good for human health.

Tran Thuc in Ha Dong district in Hanoi confirmed that she used dried mangosteen peels to treat her younger brother who had diarrhea last week. 

“The mangosteen was dried last year after I read an article about its uses. But I did not think it would be useful until my younger brother used it. It was really amazing,” she said.

Studies show that mangosteen peels have many uses. They can be used to cure diarrhea, dysentery, bad breath, irregular menstruation, freckles, and reduce cholesterol in the blood. However, the diseases need different formulas. Particularly, only dried peels, not fresh, can be used. 

On online markets, the peel is offered at VND95,000 per kilogram.

Cocoa pods used to produce liquor

In cocoa growing areas of Vietnam, after harvesting, cocoa beans are split for processing, while a small part of the pods are dried and burnt. The remaining pods and flesh are thrown into rivers or tree roots for natural decomposition, which causes environmental pollution.
