The white petals are shorter than the green sepals. Very common around dwellings. Any form of internal inflammation is soothed and healed by application of chickweed as an external poultice. Fresh chickweed leaves are so soft and tender that it is possible to macerate them with your thumbnail into a green pulp. Apply this pulp fresh every hour or so and hold it in place with a bandage.
Some herbalists prefer to cover the fresh herb with boiling water, cool it a bit, and then apply.
Chickweed is also used for burns, skin diseases, sore eyes, and wounds. A salve of chickweed powder may be applied in addition to bathing with chickweed tea and drinking the tea. In a word it comforteth, digesteth, defendeth, and supporateth very notably. A vaginal bolus formula from Christopher that I have modified and used includes chickweed along with squaw vine herb, slippery elm bark, comfrey root, yellow dock root, golden seal root, mullein, and marshmallow root, with cocoa butter to hold them all together. Wrap with gauze to form a tampon and replace three times a day.
