Portulaca oleracea is a common Chinese medicine with sour taste and cold nature, belonging to the liver and intestine meridian. It has the effects of clearing away heat and toxic materials, cooling blood, stopping bleeding, and stopping dysentery, and is usually used to treat heat-toxic blood dysentery, carbuncle, furuncle, eczema, erysipelas, and snake bite. However, when Portulaca oleracea is old, its nutritional value will decrease and its taste will deteriorate, so it is generally not recommended to eat it.
It is worth noting that purslane is a cold medicine. If eaten in excess, it may cause irritation to the gastrointestinal tract, with symptoms such as abdominal pain, diarrhea and abdominal distension, which will have a certain impact on health. Therefore, when eating purslane, you need to pay attention to the right amount and don't eat too much.
