The four-leaf clover is a very special creature. It is a variation of the three-leaf grass. There is only one four-leaf clover among millions of three-leaf grasses. Therefore, the four-leaf clover is regarded as a symbol of luck and is also given many beautiful stories. Many boys and girls will go looking for it, and will be very happy when they find it. They will make it into a bookmark and give it to the person they like. Finding a leaf among millions of leaves is fate, just like meeting each other among millions of people.

Four-leaf clover is a type of trifoliate acid, belonging to the Oxalidaceae family, Oxalis genus. Its scientific name is Oxalis, and it is also a traditional Chinese medicine. "Yi Lin Zong Yao" states: "(Oxalis) can boil red copper to white, and its ability to remove blood stasis is known. Its sour taste is three times that of liver wood, and its opening and closing should be in the morning and evening, which is the regulation of lung metal. Sourness is astringent, and its opening and closing should be timely, so it can replenish lung metal and clear liver fire, so that qi is calm and blood does not flow indiscriminately. It can treat vomiting blood, epistaxis, all kinds of reverse blood stasis, blood heat, carbuncle poison, and burns. Don't ignore it because it is cheap."

That is to say, Oxalis sorrel opens the liver and lung meridians, and has the effects of clearing heat and cooling blood, and astringing and stopping bleeding. We cannot ignore its role just because it grows in wasteland, fields or roadsides. If you are bitten by snakes or insects in the mountains, you can find Oxalis that you can chew and apply externally to clear away heat and detoxify. It can cure mild symptoms and delay the development of toxins in severe cases, thus buying time for treatment.

Oxalis is sour, astringent and cold in nature, and enters the liver, lung and bladder meridians. It has the effects of clearing heat and dampness, cooling blood and dispersing blood stasis, detoxifying and reducing swelling. It is mainly used to treat diarrhea due to damp heat, dysentery, jaundice, stranguria, leucorrhea, hematemesis, epistaxis, hematuria, irregular menstruation, bruises, sore throat, carbuncles, furuncles, erysipelas, hemorrhoids, burns, snake and insect bites, etc.

Every Chinese medicine is a gift from nature, and we should try our best to understand its effects and recognize its appearance. The lucky clover may really bring luck.
