There is a fat doll in my house. Does anyone know his scientific name? Is it poisonous?

It's Vason. Vason, alias acid, is a strange plant. It grows on sand dunes, cracks or old roofs, but it looks different from ordinary desert plants. Its stems and leaves are neither hairy nor spiny, but fleshy green. So they are called "fat dolls". Vasong is another herb, which tastes sour, flat and slightly toxic. It can stop bleeding, stop dysentery and heal sores. Bake the whole grass, water or decoct it, and treat dysentery. External application of mashed juice to treat scald. Adding brown sugar to wasong juice, drying in the sun after solidification and taking orally can stop nosebleeds. No poison.
