Chinese Herbs – Shi Hu (Herba Dendrobii)

Shi Hu is also known as dendrobium. The sweet, bland and slightly cold herb has been used in TCM to treat thirsty, thromboangitis obliterans, chronic throat infection, blurry vision, weak lower back, etc., as it nourishes the Stomach and Yin, promotes generation of Body Fluids, clears Heat, etc., by enhancing the functions of lung and stomach channels.

Ingredients
1. Ophiopogonin
2. Ruscogenin
3. β-sitosterol
4. Stigmastero
6. Nobilonine
7. 6-hydroxydendrobine
8. Etc.

Health Benefits
1. Stomach-heat syndrome
In the study to observe the effects of Herba dendrobii on rats with stomach-heat syndrome and to explore the mechanisms, showed that HD relieves the general symptom and sign the gastric mucosa of rats with stomach-heat syndrome is that HD can increase 6-keto-PGF1alpha and decrease IL-8, Gas, TXB2 in their blood(1)
2. Novel neuronal therapeutic agent
In the study of the effect of PJBH extracts on H2O2-induced toxicity in the rat pheochromocytoma line PC12 was examined by measurements of cell lesion, level of lipid peroxidation and antioxidant enzyme activities of Paeng-Jo-Yeon-Nyeon-Baek-Ja-In-Hwan (PJBH) prescription, a dried decoctum consisting of a mixture of 18 medicinal herbs that include Semen Biotae, Fructus Torilis seu cnidii, Fructus Rubi, Herba Dendrobii, Radix Morindae officinalis, Cortex Eucommiae, Radix Aspragi, Radix Polygalae, Radix Dipsaci, Ramulus Cinnamomi, Rhizoma Acori graminei, Rhizoma Alismatis, Rhizoma Dioscoreae, Radix Ginseng, Radix Rehmanniae preparata, Fructus corni, Fructus Schisandrae and Herba Cistanches.
Indicated that the effects of the PJBH on hydrogen peroxide-induced injury in PC12 cells were also examined. PJBH had a remarkable elevating effect on catalase and GSH-Px activities as well as cell survival, suggesting that cytoprotective effects of the PJBH are involved in stimulation against intermediate concentrations of H2O2-induced PC12 cell injury. The above-mentioned neuroprotective effects were also compared with the effect of tacrine. The results suggest that PJBH has potential for use as a novel neuronal therapeutic agent(2).
