Tea, which grows as a bush and is cultivated in many parts of the East, is familiar to everyone. The tea plant is sometimes called Assam tea, black tea, China tea and green tea, though these names are usually reserved for the various beverages made from the leaves (which also include sencha, matcha, oolong tea, white tea and pu-erh tea), and often to the processes used in production. The latin name is Camellia sinensis (syn. Camellia bohea, C. thea, C. theifera and Thea sinensis). It is not related to the tea tree.
The tea bush is an evergreen shrub, reaching a height of 13 feet (4m) and spreading over 8 feet wide. However, as it is only the tips which are used, it is usually kept trimmed to a more manageable size.
In common with other Camellias it will not grow in alkaline soil and is virtually allergic to lime and chalk, to such an extent that care must be taken when sourcing water to be used for it. It prefers a semi-shady position on well drained moist soil. It is not very hardy, surviving at temperatures as low as -20ºC (-4ºF) – zone 8 – in its native area, but only down to around -10ºC (-4ºF) elsewhere.
The parts used are the very young leaves and leaf buds of bushes over 3 years old, which can be harvested throughout the growing season and dried for later use. This is called green tea. You can also use good quality commercial green tea, which is readily available.
Green tea is different from other kinds of tea on the market, because the leaves are not fermented during processing. This makes green tea the most natural type of tea, and it is also the one which contains the highest levels of antioxidants (polyphenols) and other constituents.
Tea is one of the 50 fundamental herbs in Chinese herbalism. Studies have shown that regular tea drinking protects against heart disease and also tooth decay! Use internally to treat diarrhea, amebic and bacterial dysentery, hepatitis and gastro-enteritis, as a diuretic, stimulant and heart tonic. You can use the leaves or teabags as a poultice to treat cuts, burns, bruises, insect bites, swellings, tired eyes etc. Cold tea can be used as a wash for the same purposes and for sunburn.
There have been many studies into the properties of green tea, and these indicate that green tea is effective against auto-immune conditions including ALS (Lou Gehrig`s disease), cancer and heart disease. Anybody suffering from an auto-immune condition (which includes many chronic diseases such as diabetes and rheumatoid arthritis, as well as more serious problems) would probably find that drinking 2-4 cups of green tea a day will help. It certainly can’t hurt!
I offer many types of tea, including supplements in my online shop.
If you wish to grow it yourself for herbal use do ensure that you follow organic methods to avoid the corruption of its intrinsic components by foreign chemicals. To find out more about growing organic herbs visit the Gardenzone.
