LONGECITY

Extension of lifespan in mice treated with Dinh lang (Policias fruticosum L.) and (-)deprenyl.
http://www.ncbi.nlm..../pubmed/1304677

I don't seem to be able to find the full study, but this looks interesting?

Its been mentioned here before with little interest:

From the link in the old post:

Dinh lang extract and deprenyl have some additive effects on prolonging the lifespan of OFA-1 mice. (Acta Physiologica Hungarica 79(2): 119-124 1992)

                Maximum Lifespan

control     133 weeks

dinh lang 170

deprenyl  162

both         180

This also works in Wistar rats as well. (Acta Physiologica Hungarica 75: 301-302 1990)

          Average     Maximum

          Lifespan     Lifespan

control      147     164 weeks

dinh lang  180     194

both          206     239

The life extending effect of dinh lang extract appears to be quite real as it has been demonstrated in two strains of rodents. Moreover dinh lang appears to be more effective than deprenyl.

In addition the dosage used was probably sub-optimal. Only 10 mg/kg extract was used in the life extension experiments, while maximal effects of passive avoidance performance in young OFA mice was found at 20 mg/kg. (Acta Physiologica Hungarica 75(1): 69-76 1990)

In Wistar rats aged 22-24 months 20.8% resumed full scale sexual activity at a dosage of 20 mg/kg, 11.5% at 10 mg/kg, 7.7% at 5 mg/kg and 0% for controls. (Acta Physiologica Hungarica 75(1): 61-67 1990)

It would be interesting to see more research on dinh lang, especially at the 20 mg/kg dosage.

I have find a company for selling đinh lăng pill in 越南.  Don't know if they will sell and ship oversea?
