Traditional medicine holds that potatoes can strengthen the spleen and stomach, reduce inflammation, and dissipate nodules. For certain specific ailments, the therapeutic effects of raw potato juice in food therapy are well-regarded, such as its good auxiliary effects on gastritis and gastric ulcers.
It also contains a large amount of special protective mucoprotein, which helps prevent the occurrence of atherosclerosis. Fresh potatoes used for food therapy should be juiced without the need for heating or cooking, but they must be consumed immediately after juicing and cannot be stored. Children with incomplete gastrointestinal function should drink it with caution. It is also advisable to wait half an hour after drinking before eating, to avoid diluting gastric juice and affecting digestion. Additionally, potatoes contain a slight toxic alkaloid; the human body should not intake too much of it, so it is best to peel the potatoes before juicing.
