I have posted about this before but I'll post it again. Adaptogenic herbs have much to offer us, pedes. I'll just lead off with this article. This cites some of the old Russian research on Siberian Ginseng AKA Eleutherococcus Root.
Just thought I'd leave this article here. This is from May 2002. http://www.positivehealth.com/article/herbal-medicine/adaptogen-eleutherococcus-senticosus-maxim-shrub
"In the 1970s 1,250 drivers at a Russian automobile plant were given twice-yearly courses of Eleutherococcus. The work that they did was repetitive and stressful in a difficult industrial environment. After one year the percentage of sick workers was reduced by 30%, and the total disease incidence in the control group was unchanged. At the same plant in November to December 1975 a total of 13,096 workers took Eleutherococcus daily with a resulting 30% to 50% reduction in illnesses such as respiratory tract infections and influenza, as compared with the control group. A seven-year study of truck drivers, again in Russia, reported an amazing 90% reduction in the incidence of influenza-type illnesses. "
As you can see, this is an essential ingredient in any witch doctor's medicine kit.
Goes great with Ginkgo biloba (natural quercetin content) and elder flowers (lots of zinc and other good stuff), mixed up in tea. I drink it every day and have not had so much as a sniffle.
Seriously, pedes, start doing research on "adapogenic" herbs. These include: eleutherococcus root, astragalus root, cordyceps fungus, Ocimum tenuiflorum, reishi mushroom, chaga mushroom, and other herbs which herbalists typically refer to as "adaptogens".
There's tons of good info out there. Be careful when mixing these kinds of herbs in high doses though, just want to advise you guys of that in advance. Always start with small amounts, and add in one new supplement at a time when using any supplement regimen. You may want to consult your personal physician as well, as long as you can find one you trust.
