Lacria is a traditional Chinese medicine composed of six herbal ingredients, including Stephania tetrandra, Astragalus membranaceus, and Atractylodes macrocephala, which work on water metabolism, and Ziziphus jujuba and Zingiber officinale, which improve digestive and absorptive functions. By working on water metabolism and regulating digestive and absorptive functions, it helps the body circulate water on its own, thus improving obesity (water retention) in people who sweat a lot while excreting excess water as urine. It also helps to lighten a heavy, sluggish, and swollen body.
