St Joan's (John's) Wort/ Hypericum perforatum.
A well known antidepressant, Hypericum is also often used to prevent and treat herpes outbreaks and other skin irritations; in addition to providing pain relief and improving mood.
I harvest the fresh flowers and make the infusion using 80 proof vodka. (I typically use 100 proof, but felt this particular container of vodka was too perfect for a tincture that helps the brain.)The process takes at least 6 weeks. Tinctures have a shelf life of a several years or more.Available in 1oz and 2oz glass bottles.
