I'm drinking Lipton Chamomile Tea every night. And PureHerbs LemonGrass Tea every after 2days. Is it safe? These teas are from teabags

Pesticides & toxins. While chamomile and lemongrass are very safe, many teas are contaminated with significant levels of pesticides and the teabags can contain epichorohydrin, a carcinogen. Thus, get these teas only as organic from companies with safe teabags such as Numi, Rishi and Yogi (or get as organic loose tea & use tea ball).
