Blue Vervain
Verbena stricta
A plant that delivers a calming, centering effect to adults as well as children. Linda Black Elk very comprehensively describes the effects of tea made of the entire above ground parts of Blue Vervain from personal experience. Whether for autistic excitability or just for the out-of-sorts feeling we all get sometimes, Linda spells out the calming influence this plant exerts on us.
Linda also helps us identify this species which looks like it may be in the mint family (Lamiaceae) due to its opposite leaves but actually is in its own family – Verbenaceae.
