Herbs are frequently used as teas or infusions. Although there are no clinical trials available, and there is no evidence-based proof in terms of Western medical standards, some herbal teas/infusions have been used for many years without adverse effects, and arc considered to be safe. The evidence of their safety comes from their traditional use and from traditional evidence passed down through history by traditional users. Although there are no data to suggest how much is "safe", it is suggested that consumption of herbal teas be limited to two cups per day during pregnancy. This is similar to the safety data regarding coffee in pregnancy. Their safety is unknown when used at higher levels, so the use of herbs above these amounts is not recommended. If the quantities consumed are above these recommended levels, no special action is required except stopping usage at high doses. (See Low Dog 2005, Blumenthal 2003, Weed 1986.).
Table 2.19.2 lists those herbs that arc frequently used during pregnancy.
