Organic tea is becoming more and more expected for tea drinkers. Because the tender leaf of the Camellia Sinensis is not washed after picking, it is important to know there are not harmful pesticides and other chemicals on the tea leaves during processing. It is also important to know where the tea you drink is from. Tea plants grown in heavy industrialized areas in China can have elevated levels of lead in the soil translating into the minute levels in the tea leaves. Although they claim that the levels are not considered to be dangerous for tea drinkers, it is still something to be aware of.
