Black nightshade berries are sweet and sour, a wild fruit often eaten in childhood; solanine poisoning can cause death within 24 hours
When I was little, I loved going out with a few friends to dig up cogongrass roots and look for this sweet fruit to eat! We were used to calling it heiduluer, but actually it also has a high-end, impressive name, "black nightshade"
Black nightshade is also known as bitter herb, heiduluer, goufuzi, bitter nightshade, little eggplant, tiandidou, niaoguicao, houhongzi, dipaozi, heitiantian, tianqiezi, tiantianqie, erzhui cai, and so on. It has spherical berries that turn blackish-purple when ripe. Black nightshade is an annual herbaceous plant, with the whole plant reaching 30-120 cm tall; the stem is upright and much branched; the ovate or heart-shaped leaves are alternate and nearly entire; in summer it bears small white flowers, 4-10 in umbel-like cymes.
Black nightshade contains toxic substances such as solanine and solanine alkaloids. Although it can be eaten raw, when eating it, it must be blanched and soaked in boiling water to remove the toxic substances before it can be eaten. Black nightshade can treat acute nephritis, bruises and sprains, erysipelas, chronic bronchitis, and other symptoms. After blanching, black nightshade can be chopped to make dumpling filling, or used in cold dishes. Besides that, it can also be stir-fried with eggs, or simply stir-fried and eaten; the taste is actually quite good.
Black nightshade has strong antioxidant properties, and cancer patients are well suited to eat it. Cancer is usually caused by a combination of heat toxin, blood stasis, yin deficiency, and qi stagnation. Heat toxin is usually caused by external toxins entering the human body. The whole plant is used as medicine to treat digestive tract cancer, lung cancer, and so on.
Research has found that black nightshade has an inhibitory effect on mouse cervical cancer U14, sarcoma S180, and the solid form of Ehrlich ascites tumor. Compound black nightshade injection has a clear inhibitory effect on the proliferation of mouse liver cancer (H22) ascites-type cancer cells, with a cancer inhibition rate of 87.4%. At the same time, the activities of phosphodiesterase and Na+-K+-ATPase on the surface of cancer cell membranes both decreased. The microvilli on the membrane surface noticeably receded. The total alkaloids extracted from the dried green fruits of black nightshade had an inhibition rate of 40%-50% on transplanted animal tumors.
