The main ingredient, betel nut, is produced in the mountains of Chiayi. The betel nut alkaloid within the betel nut has moisturizing properties. An appropriate amount of betel nut extract can have anti-allergic effects on the skin. The biggest feature of betel nut soap is its oil control and exfoliating properties for skin conditioning. Especially for skin with external wounds, regular body wash or shampoo can cause discomfort to the wound, but washing with betel nut soap does not cause discomfort or inflammation. It has higher moisturizing properties and is very helpful for body cleansing. Recommended souvenir: Luo Jia Zhuang Betel Nut Soap. Address: 嘉義市西區友愛路 349 號 Hours: 00:00–23:59 Chiayi
