Objective: To evaluate bi-directional modulation effect of Chinese herbal medicine on immunol cells.
Method: Two different active portions were isolated from Kudzuvine Root(Radix puerariae), one being the ethanol extraction and another the water extraction. Different concentration of these two different portions was studied by using PMA stimulated lymphocyte or eosinophil initiated chemiluminescence system.
Result: Water extraction of Kudzuvine Root could enhance chemiluminescence concentration dependently whereas enthanol extraction of Kudzuvine Root inhibited the chemiluminescence significantly.
Conclusion: The bi-directional regulation effect of Chinese herbal medicine can be found in the same herb, because of its efficacy of different active compounds.

Diabetic kidney disease (DKD) is a common complication of diabetes and has become the leading cause of end-stage kidney disease. The pathogenesis of DKD is complicated, and oxidative stress is considered as a core of DKD onset. High glucose can lead to increased production of reactive oxygen species (ROS) the polyol, PKC, AGE/RAGE and hexosamine pathways, resulting in enhanced oxidative stress response.

Catalpol and puerarin are two monomers of and , which are two herbs commonly used together in ancient prescriptions of traditional Chinese medicine for cerebral ischemia. Our previous study shows that the lyophilized powder of the two monomers improved the outcome of cerebral ischemia excellently in rodents. However, if it protects vessels from ischemia is unknown.

Ethnopharmacological Relevance: With the mounting pandemic of glucose metabolism dysregulation and type 2 Diabetes Mellitus (T2DM), traditional medicine such as traditional Chinese medicine (TCM) recipes has been widely adopted as a part of therapeutic approach, especially in Asian countries.
Aim Of The Study: A novel approach, which is adopted from cohort studies from epidemiology has been applied to explore the clinical efficacy, as well as the herbal component selection of a variety of TCM formulations against T2DM.
Materials And Methods: In the current study, 98 newly diagnosed T2DM patients were recruited in two hospitals.

Abnormally increased levels of iron in the brain trigger cascade amplification in Alzheimer's disease patients, resulting in neuronal death. This study investigated whether components extracted from the Chinese herbs epimedium herb, milkvetch root and kudzuvine root could relieve the abnormal expression of iron metabolism-related protein in Alzheimer's disease patients. An APPswe /PS1ΔE9 double transgenic mouse model of Alzheimer's disease was used.
