Q&A for How to Decaffeinate Tea

Too much caffeine is bad for your health and can cause symptoms like insomnia, anxiety, increased heart rate and nausea, so always drink it in moderate amounts.

As with everything, when consumed in moderate, not so much. It's actually been associated with some positive effects, like uplifted mood and increased focus. However, even some small doses have been shown to have negative effects on the body, such as anxiety and raised blood pressure. Talk to your doctor, but moderate use of caffeine shouldn't have many negative effects.

Tea leaves contain caffeine naturally. Herbal teas do not contain tea leaves. They may contain other leaves, like peppermint or spearmint, but are made from herbs, roots, berries, etc. You are correct that tea leaves are plant material. The article meant that herbal teas do not contain tea leaves specifically.

You should ask your doctor. The anecdotal answer is maybe. Some people experience irregular or increased heart beat from one cup of coffee. Others drink 10 with no problem. you can experiment on yourself, or ask your doctor for advice (the latter being the most sensible option).

This is a deceptively complicated question. Tea has more coffee per pound of leaf compared to per pound of coffee bean. But you need more ground coffee to brew a single cup than you do for coffee, so a cup of tea will generally have less caffeine than a cup of coffee.

It depends on what the bladder problem is. Tea is generally good for the kidneys, so it won't hurt.

It naturally occurs in tea leaves, with black tea containing the most(75mg of caffeine per cup ). Some manufacturers make the tea leaves go through a process called carbonization where they go through high temperature and as a result the caffeine will naturally separate because of the intense heat leaving behind decaf tea leaves.
