The Voynich Botanical Plants

Folio 30r, Healall (Prunella vulgaris), is a common herb found in pastures throughout Europe. The stems of the linear leaves are attached in pairs down the main stem. The cylindrical flower spike, unlike most flower spikes, maintains its shape as it grows in length. The plant propagates from a creeping stem, that sends out roots when a new flower spike forms. Ancient herbalists used to wash wounds and ulcers with an infusion of healall. It is currently being investigated as a possible treatment for herpes.
