Common hogweed

The roots and the leaves are aphrodisiac, digestive, mildly expectorant and sedative. The plant is little used in modern herbalism but has been employed in the treatment of laryngitis and bronchitis. A tincture made from the aerial parts of the plant has also been used to relieve general debility, though it is uncertain how it works. The plant is harvested as it comes into flower and can be dried for later use. Source: https://pfaf.org/
