[Lu Gen (Rhizoma Phragmitis)]
Clears heat and stops vomiting.
Sweet in flavor benefits the Stomach; cold in nature descends fire.
Treats vomiting, hiccups, and regurgitation (due to stomach heat rising, causing rebellious qi and vomiting with difficulty in eating. *Jin Gui Yao Lue* formula: decoct Lu Gen alone for administration); treats Xiao Ke (wasting-thirst syndrome) and exogenous heat; treats internal heat from Shang Han (cold damage); reduces frequent urination (The Lung is the upper source of water metabolism; the Spleen disperses essence upwards to the Lung, thereby regulating water passages and transporting fluids downwards to the Bladder. The Kidney is the water organ, governing both urine and stool. Heat in the Lung, Spleen, and Kidney meridians causes frequent urination, even inability to hold it briefly, due to the rapid nature of fire. Lu Gen is hollow, thus entering the Heart and Lung meridians to clear upper Jiao heat; once heat is resolved, Lung Qi transformation functions normally, and urination returns to its regular course). It can detoxify fish, crab, and pufferfish poison.
Select thick, tender rhizomes growing near water; remove roots and nodes, using only the internodes.
[Ba Jiao Gen (Radix Musaens)]

Its juice can transform coagulated blood into liquid.
Using Ramie root (*Broussonetia papyrifera*) as a pillow for postpartum women helps stop bleeding and promote uterine contraction; applying it to the abdomen stops postpartum abdominal pain (utilizing its stasis-dissipating effect). Fermented ramie juice treats Xiao Ke (wasting-thirst syndrome).
