Cow-plant

Chambers's Encyclopaedia, Volume 3: Catarrh to Dion, p. 536

Cow-plant (Gymnema lactiferum), a perennial Asclepiad of Ceylon, which has acquired a factitious celebrity from the oft-repeated statement that its milky juice is used as milk, and that its leaves are boiled to supply the want of cream! But this, according to Sir J. E. Tennent, arises entirely from the appearance of the juice, which indeed probably contains a share of the poisonous principles so general in this order.
