Firewood was brought in back in April, and by the end of May, grass like this had grown near the logs:
My neighbor said it's pinworm, a very medicinal plant that she personally uses to treat bronchitis, colds, and so on. She makes decoctions and drinks them. She says it has an expectorant effect, relieves inflammation, and reduces spasms when coughing.
I certainly enjoy using traditional medicine, but within reason. So I looked at the Russian Federation Register of Medicines and discovered that pinworms simply aren't listed. Moreover, they're a very harmful weed that ruins forage crops, choking them out. They're not eaten by livestock, and if you walk over a pinworm while wearing pants, its rough leaves will definitely stick to you.
Another name for pinworm is asperuga. Caucasians are said to use the young leaves as a spicy seasoning, but to be honest, I didn't detect any pleasant aroma—it just smelled like grass. I didn't risk trying it because official pharmacology and medicine don't recognize this harmful weed as a medicinal plant. Therefore, I don't recommend anyone use this weed for medicinal purposes.
