Chickweed Materia Medica

Chickweed Materia Medica

The name chickweed originated from its use as a feed to birds especially young chickens. It has been used for centuries as a feed, but also as a tonic to cleanse the liver and kidneys. It was introduced in Eurasia and is now wide spread throughout North America including the alpine strain of chickweed. The alpine strain is called field chickweed and grows from Alaska to Colorado.

Chickweed grows well in shady and moist areas. It has a weak stem with tiny white flowers that bloom in late winter and leaves that grow all along the stem. It makes a great ground cover because of its tendency to grow outward instead of upward. Chickweed is a sign of fertile soil; the plant helps the soil to retain nitrogen.

While doing my own experiments with the herb I found it to be very supportive in helping to relieve skin issues. Its ability to help to cleanse the liver helped to reduce my skin’s irritation and acne breakouts. I also had a test subject apply the herb topically in the form of infused oil. They applied the oil about 5 times a day directly to the psoriasis affected area and reported the use of the oil relieving the itching, drying and making it less scaly.
