The plant today
Momordica charantia (commonly called bitter melon, gouya, cerassee, goya, bitter apple, bitter gourd, bitter squash, balsam-pear, karela, karavila and many more names listed below) is a tropical and subtropical vine of the family Cucurbitaceae, widely grown in Asia, Africa, and the Caribbean for its edible fruit. Its many varieties differ substantially in the shape and bitterness of the fruit. Its native range is distributed from Tropical and Subtropical Old World to South Pacific. Bitter melon originated in Africa and Asia, where it was a dry-season staple food of ǃKung hunter-gatherers.

Sa Tagalog
Ang Momordica charantia (katawagang pang-agham), ampalaya o amargoso (Ingles: balsam apple, bitter gourd o bitter melon) ay isang uri ng gulay na tumutubo sa mga tropikal na bansa tulad ng Pilipinas at iba pang parte sa Asya at Timog Amerika. Gamot ito para sa mga taong anemik dahil sa katangian nitong makapagdagdag ng dugo sa katawan. Mayroon itong makulubot na balat at mapait sa panlasa kapag kinain.

What the 1901 book says
A historical record, quoted as printed. Doses and remedies here are not medical advice.
The book gives one account for this plant and Balsam apple (Momordica balsamina), so the text below appears on each page.
Uses
The fruit of both varieties is edible, though a bitter principle gives it such an intensely bitter taste that it is intolerable to the unaccustomed palate. It is eaten raw as a salad, or cooked with meat or fish. The juice of the leaves is prescribed internally as a purgative and anthelmintic. In Concan it is given alone or combined with aromatics, in bilious disorders as an emetic and purgative; externally they use it as an ointment for the itch and other skin diseases; in India it is mixed with cinnamon, pepper, rice and oil of Hydnocarpus inebrians, Vahl.
The fruit and leaves are used internally for worms and externally for leprosy. Some Hindoo writers state that the fruit is tonic and stomachic, and that it is useful in rheumatism, gout, diseases of the liver and spleen.
