The rambutan fruit, in addition to its high nutritional value due to its rich content of vitamin C, proteins, fats, and trace elements such as copper, manganese, potassium, calcium, iron, and phosphorus, is also used as a medicinal remedy.
Green rambutan fruit and its peel, which contain a lot of tannins, are used to treat diarrhea, dysentery, and fever in doses of 20 g – 30 g. To reduce fever, you can take 15 g of cleaned rambutan peel, boil it, and drink it several times a day. To treat dysentery, use 10 rambutan fruits, chop them up, and boil them to drink twice a day.
Rambutan seeds (also known as "thiều tử") have a sweet taste and warm nature. They contain many unsaturated fats, such as olein and arachidic acid (36.26%), and have anti-inflammatory and antibacterial effects. They are used to treat diabetes, oral mucositis, dysentery, chronic ulcers, regulate blood lipids, reduce fat, and improve skin health. To lose weight, you can eat rambutan seeds raw or roast them and mix them with other foods.
With its ability to regulate blood lipids, reduce fat, and being very rich in vitamin C, rambutan is an excellent fruit for those suffering from arteriosclerosis, high blood pressure, and elevated blood sugar levels. However, because rambutan seeds contain a lot of fat, consuming too many can lead to dizziness, nausea, and bloating.
