    Asparagus Root (Tian Men Dong) is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Excellent Dong! My wife needs to take tian men dong daily. We had been taking a tincture from a small place that made it by hand that worked wonders, but of course, they either closed up or stopped making it. We never found out what happened because their customer service was horrendous to say the least. So we started searching for dong everywhere and tried many different brands. Our herbal doctor told us to have her try the ActiveHerb dong, and I’m so glad we did. It has been just as effective as the other stuff, and at a much more reasonable price. We will continue buying this dong as the quality of it is perfect. She just adds a small scoop of the dong to hot water with a bit of honey and takes it as a tea. We would highly recommend, and have already told several friends about this high quality dong.
