The plant today
Maize (; Zea mays), also known as corn, is a tall stout grass that produces cereal grain. The leafy stalk of the plant gives rise to male inflorescences or tassels which produce pollen, and female inflorescences called ears. The ears yield grain, known as kernels or seeds. In modern commercial varieties, these are usually yellow or white; other varieties can be of many colors. Maize was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte. Native Americans planted it alongside beans and squashes in the Three Sisters polyculture. Maize relies on humans for its propagation.

Sa Tagalog
Ang mais (Zea mays) ay isang mataas na matabang damo na nagbubunga ng butil na angkak. Dinomestikado ito ng mga katutubo sa timog Mehiko noong mga 9,000 taon na ang nakalilipas mula sa ligaw na teosinte. Itinanim ito ng mga katutubong Amerikano kasama ang priholes at kalabasa sa polikulturang Tatlong Magkakapatid na Babae.

Uses
Corn is an extensive article of diet in the Philippines, but has the reputation of being indigestible. This is true when it is eaten in the grain, but in the form of meal it is easily digested and highly nutritious. The tassels have been used in the Philippines from time immemorial in decoction as a diuretic, for which property they received notice in the Medical World of Paris about the year 1876. The entire plant is diuretic and the natives give the decoction of the stalk for various diseases of the bladder and kidneys. An extract of the tassels has been put on the market, but it is better to administer a decoction made from 20 grams of tassel to 1 liter of water to be taken at will during the day. Rademaker and Fischer give the following chemical composition:

The fixed oil is bright yellow, saponifiable by potash, soluble in chloroform and ether, insoluble in alcohol, solidifies at 10°.
