The efficacy and function of sweet potato vine

Sweet potato heads are the rhizomes and leaves of sweet potatoes. Although they are withered and yellow, they have high medicinal value. It is not as simple as throwing them away. People who understand them can preserve them to treat blood problems, purify the blood, prevent high blood pressure, high blood lipids, and relieve constipation and hemorrhoids.

Sweet potato leaves, which are the tender leaves at the top or both sides of the aboveground sweet potato stems, can be harvested in all seasons in the south. Common sweet potato leaves include chicken claw-shaped, five-claw-shaped, heart-shaped, etc. The petioles are blue, green, and purple. Tests on sweet potato leaves have shown that every 100 grams of fresh sweet potato leaves contain 2.28 grams of protein, 0.2 grams of fat, 4.1 grams of sugar, 16 milligrams of the mineral potassium, 2.3 milligrams of iron, 34 milligrams of phosphorus, 6.42 milligrams of carotene, and 0.32 milligrams of vitamin C. Compared with common vegetables, its content of minerals and vitamins is superior, and its carotene content is even higher than that of carrots. Therefore, the Asian Vegetable Research Center has listed sweet potato leaves as a high-nutrition vegetable variety, calling it the "Queen of Vegetables." In recent years, there has been a "sweet potato leaf fever" in Europe, America, Japan, Hong Kong and other places.
