Yerba Mate makes a good houseplant that provides leaves for tea.

Grow you own Yerba Mate and enjoy this popular South American tea as an alternative beverage to coffee. In Latin America, Yerba Mate is the beverage of choice and has a smoother taste than green tea, plus it's loaded with antioxidants. The plant itself makes a wonderful potted plant for its graceful full-leafed branches. Under warm temperatures, it grows throughout the year, even in the north as a potted plant with flowers arriving during the winter/spring months. The leaves can be harvested once the plant is established. Grow in full sun with temperature above 65 degrees for fastest growth.
Hardy to Zone 10 and higher for outdoors.
Yerba mate was has been used as a beverage since the time of the ancient Indians of Brazil and Paraguay. In the early 16th century, Juan de Solis, a Spanish explorer of South America's famed La Plata River, reported that the Guarani Indians of Paraguay brewed a leaf tea that "produced exhilaration and relief from fatigue." The Spaniards tried the beverage and liked it. Their subsequent demand for the tea led the Jesuits to develop plantations of the wild species in Paraguay and yerba mate became known as "Jesuits' tea" or "Paraguay tea."
Methods of leaf preparation for the traditional tea beverage vary then and now: in one method, the branches are cut, then held over an open fire (to fire-cure the leaves). This deactivates the enzymes in the leaves (making them more brittle) and the green color of the leaves is retained in the subsequent drying process (with charred bits often found in the resulting tea product, which lends to a smoky flavor). Other methods include a brief par-blanching of the leaves in boiling water (to deactivate the leaf enzymes and soften its leathery texture). They then are toasted dry in large pans over a fire or inside a brick oven-resulting in a finished brown-leaf tea.
The wild plant has a distinct aroma and taste that has not been matched by plantation cultivation. In South America yerba mate is considered a national drink in several countries; in Europe, it is called "the green gold of the Indios." In Brazil and Paraguay (leading exporters of mate), some production still comes from wild stands-most of which is found in the humid depressions of the foothills. It is not unusual for one wild tree to yield 30-40 kg of dried leaves annually. In wild harvesting, mate gatherers, called tarrafeiros or yebateros, travel through the jungle searching for a stand of trees (called a mancha). Harvesting is done between May and October, when the tree is in full leaf. Leaves are picked from the same tree only every third year, which protects it for subsequent crops. Most of the mate in commerce today, however, comes from large cultivation projects in Paraguay and Uruguay.
The word mate is Spanish for "gourd," and refers to the small gourd cup in which the tea beverage traditionally is served throughout South America. It is also served with a metal drinking straw or tube, called a bombilla, which has a filter attached to the lower end to strain out leaf fragments. The bottom third of the gourd is filled with fire-burned or toasted leaves, and hot water is added. Burnt sugar, lemon juice, and/or milk often is used to flavor the refreshing tea, which occupies a position rivaling that of coffee in the United States. Mate bars are as prevalent in South America as coffee bars are in North America and Europe; mate drinking has deep cultural roots.
In addition to its standing as a popular beverage, yerba mate is used as a tonic, diuretic, and as a stimulant to reduce fatigue, suppress appetite, and aid gastric function in herbal medicine systems throughout South America. It also has been used as a depurative (to promote cleansing and excretion of waste). In Brazil, mate is said to stimulate the nervous and muscular systems and is used for digestive problems, renal colic, nerve pain, depression, fatigue, and obesity. A poultice of the leaves also is applied topically to anthrax skin ulcers (for which mate's tannin content - highly astringent - may be the reasoning behind this use).
