This, sometimes necessary substance, is found in high quantities in coffee. Lower amounts are found in tea, with black and oolong tea having a higher caffeine content than green or white.
Caffeine in small quantities can be useful for improving concentration and athletic ability. It is important not to consume excess quantities though, as this can lead to dehydration, and may also affect the adrenal glands and liver.
Polyphenols are a type of antioxidant which are found in various forms across a wide range of plant based foods.
The types of polyphenol most commonly found in tea are hydroxybenzoic acids.
Polyphenols are renowned for their health benefits, which include fighting free radicals, reducing inflammation, and supporting the cardiovascular system.
A bitter compounds with a strong astringent action, tannins are a type of polyphenol, and are found abundantly in tea and wine, and also in some herbs such as geranium or wattle.
Tannins are responsible for the dry feeling on your tongue. They dissolve easily in water, and the longer a tea is brewed, the higher the tannin content will be.
Antioxidants are any substance which act against free radicals. In addition to their reputation for promoting healthy skin and immune systems, they are also known for reducing the health complications of some chronic diseases.
Conditions such as diabetes, cancer, heart disease and osteoporosis can all benefit from the intake of antioxidants.
Their protective nature means that cells and organs are supported to work optimally, meaning less physical stress and illness.
Tea contains small quantities of potassium, phosphorus, fluoride and magnesium. It also has trace amounts of manganese.
These minerals are essential for healthy bones, as well as regulating the nervous system, and basic cell functions.
Herbal infusions may contain a variety of minerals, including iron, calcium, zinc and copper.
In addition to the health benefits of herbal teas, the mineral content may contribute to daily nutritional requirements.
The Nitty Gritty (Studies)
There are several studies which support the function of tea as an antioxidant, antiviral, and anticarcinogenic beverage.
- Sung et al demonstrated a significant increase in antioxidant capacity in blood plasma, when quantities over 300mL are consumed. (https://www.ncbi.nlm.nih.gov/pubmed/10918460)
- As an antiviral agent, green tea has been shown to be effective against herpes simplex, influenza A and B, rotavirus and enterovirus. (https://www.ncbi.nlm.nih.gov/pubmed/1668240)
- Extracts of green tea have been proven to reduce cell proliferation in some tumours, and it is suggested that regular consumption may even prevent the occurrence of cancer. (https://www.ncbi.nlm.nih.gov/pubmed/12494882)
Herbal teas have hundreds of years of both scientific and anecdotal evidence. For many herbs, modern studies are now supporting traditional use, proving the wisdom of long established health treatments.

White, green and black teas will become bitter if left to steep for too long. The recommended steep time is one minute, two minutes, and 3 minutes respectively.
White and green teas should ideally steep for no longer than two minutes, in hot, but not boiling water.
