Healing Properties and Uses

The tea plant leaves contain 1 to 4 percent caffeine (called theine to differentiate its origin), tannins (15-20 percent), and one essence. Tea’s effects are very similar to coffee’s, though less intense because tea infusions are prepared less concentrated. A cup of tea contains 40 to 60 mg of caffeine, and a cup of coffee contains 100 to 200 mg. Tea excites the nervous, heart, and blood systems and increases the secretion of acid juices in the stomach.

Tea’s use as a stimulant is an emergency remedy that should never become habitual in cases of tiredness or fatigue. Like coffee, tea stimulates but does not provide us with any nutritional substance. Thus, its regular use provokes exhaustion.

Habitual consumption produces a condition called caffeinism: constipation, stomach acidity, insomnia, and nervous excitation. Frequent consumption of tea causes addiction, as with any other drug.

Due to its tannin content, it is used for diarrhea and colitis and as a digestive tonic for upset stomachs or indigestion. Plenty of plants can constitute treatment for these conditions but lack the disadvantages of tea. In external use, it is employed as eyedrops for eye baths in cases of conjunctivitis.

WARNING! The tea plant must not be used continuously, not even as a medicine, because its caffeine content will provoke addiction (urge to keep on taking it) and tolerance (need to increase the dose), as happens with any other addictive drug. The  use of the tea plant is discouraged in the following cases:

• Gastric and duodenal ulcers
• Gastritis
• Pyrosis (stomach acidity)
• Nervousness
• High blood pressure
• Heart dysfunctions

Pregnant and breastfeeding women should abstain from using tea because of the toxic effects of caffeine on the fetus or the breastfeeding baby (it passes to the milk).

How to use Tea

1. Infusion with 20-40 grams per liter of water, with a maximum of five cups daily.
2. Eye bath. In cases of conjunctivitis, it is employed in a decoction with 30-50 grams of plant per liter of water. Boil for five minutes to sterilize it before applying it to the eyes.
