Hardly do people who are born and grow up in the city know “manh cong”. Those who live in the country side may not find the name familiar until seeing the leaves in their own eyes. Manh cong belongs to the acanthus family and used to be spotted in nearly every habitat, from the grandparents’ fences to village ponds. It has several strange names according to its various legends and medicinal uses including antifungal, cytotoxic, anti-inflammatory, anti-pyretic, anti-oxidant, insecticidal ones. People in the Southeast even call Manh cong “bim bip” or centrupus as they see the centrupus mother cover the broken leg of her offspring by the leaves.
