The Voynich Botanical Plants

Folio 26r, Self-heal (Prunella vulgaris), is a low growing plant native to Europe. It is a member of the mint family. The oblong leaves grow on short stalks in pairs down the stem. They are rough and their margins are fringed with tiny hairs. At the end of the stem is a spike of blue flowers, arranged in regular whorls. It has a normal spreading root. Self-heal got its name from its antiseptic and antibacterial properties, and was found to be useful in cases of food poisoning. The photograph of self-heal was taken by Lachlan Cranswick
