Chickweed has many potential health benefits, including:
Skin treatment
Chickweed can be used to treat skin conditions like eczema, poison ivy, and poison oak. It can be applied topically as a cream or salve to reduce inflammation and itching. 
Digestive health
Chickweed can soothe the digestive system, kidneys, bladder, urinary tract, sore throat, lungs, and bowels. 
Immune system
Chickweed may help activate the immune system. 
Weight loss
Chickweed is often included in herbal weight-loss formulas because it contains saponins, which can help dissolve fat cells. 
Chickweed is a common weed that grows in moist, sunny or partially sunny areas in the fall and early spring. It's high in vitamins and minerals, including vitamin C, calcium, potassium, iron, phosphorus, and manganese. You can eat chickweed raw in salads, or make it into tea, glycerite, tincture, or succus. 
However, more research is needed to confirm the health benefits of chickweed.
