Astragalus (Astragalus membranaceus) is a fairly new herb to many people. It’s widely popular in Chinese and Eastern medicine. Much like their love for ginseng, eastern herblists simply adore Astragalus root. It has been traditionally used for over 5,000 years to help boost the immune system and cure many common ailments. But did you know we can use this herb for our livestock too?
Uses of Astragalus: immune support, adaptogenic, helps body adapt to stress, antibacterial, antiviral, reduces the common cold and flu, increases white blood cell count, anti-inflammatory, protects cardiovascular system
So we know that Astragalus not only supports the immune system, but it also helps the body adapt to stress, which plays a major role in a healthy immune system. Boosting the white blood cell count is also a highly effective way to fight off illness and diseases. It is also antibacterial, and we all know bacteria are the worst when it comes to the wonderful world of chickens.
In a clinical study done by the South China Agricultural University, hundreds of chicks were infected with Avian Flu, both in the egg (in vitro) and once hatched (in vivo). Scientists studied the effects of several different treatments, including astragalus root, in a controlled environment. This is the only way to properly study treatments as there are so many factors that play a role.
From this study, the following conclusions were derived:
1. At an appropriate concentration (231.25μg/mL) APS (astragalus root) can drastically reduce the proliferation of H9N2 virus (avian influenza).
2. APS enhanced the proliferation of CEF cells when used at concentrations > 9.766μg/mL. The exception, the simultaneous addition of APS and virus at APS concentrations of 2,500μg/mL and 1,250μg/mL.
3. APS effectively increases the expression of IL-2, IL-4, IL-6, IL-10, LITAF and IL-12, promotes cell growth, and enhances anti-H9N2 activity.
4. APS promoted a rapid humoral response following H9N2 vaccine immunization or H9N2 AIV infection.
5. The appropriate dose of APS (5 and 10mg/kg) significantly enhanced the specific immune response in chickens, and improved vaccine effectiveness; promoting an earlier peak that increased rapidly and was sustained for a longer period of time.
6. The CD4+, CD8+ T lymphocyte content and CD4+/CD8+ values for all the APS treatment groups were higher than those for the untreated (no APS) control group. The values for the 5 and 20mg/kg APS dose groups were significantly higher than the control group, which indicated that the appropriate dose of polysaccharide can promote the production of peripheral CD4+ and CD8+ lymphocytes in chickens, thereby enhancing cellular immunity.
7. APS inhibited H9N2 both in vitro and in vivo.
The precise mechanisms responsible for the response to APS require further examination. On the whole, APS has the potential to diminish disease progression in H9N2 infected chickens, and its use could provide alternative strategies for the control of H9N2 AIV infection. [NCBI]
I know, it’s a lot of information, but I think for those of you who aren’t proficient in scientific talk, you can read enough in between the lines to know that astragalus root was a win. A major win.While the study concludes that more trials need to be run, it was very confident in the findings that astragalus has the potential to diminish disease progression in avian influenza infected chickens, and could provide alternative strategies for the control of avian influenza as a whole.The most surprising part, however, is that this clinical trial was done in 2013. And here we are in 2017 (at the writing of this blog), and we’ve yet to hear anything about this in the United States. Unless, of course, you’re a researching and studying herbalist like myself.All we’ve heard are the detrimental effects of avian flu on our chickens—in backyards, in poultry warehouses, on farms large and small. But we’ve not been informed that there can be a better way. That avian flu can be beat.My friends, that starts with you, and me, and all of the mini, full time, and hardcore farmers and homesteaders across the globe.
So how to we use astragalus to prevent bacterial outbreaks and viruses?
It’s simple, really.
Make an Astragalus Tincture
A typical tincture of dried herbs is used with a 1:5 or (up to) 1:10 ratio (herb:liquid) and 80-100 proof vodka, or glycerin. It is best to use dried astragalus root for this tincture.
Tincture measurement examples:
1 ounce of dried herb to 5 ounces of liquid (1:5).
3 ounces of dried herb to 15 ounces of liquid (because 3×5 [1:5] is 15 — therefore 1:5 = 3:15)
3 ounces of fresh herb to 6 ounces of liquid (because 3×2 [1:2] is 6 — 1:2 = 3:6)
Begin by measuring out your dried root and vodka in separate containers. Next, add your dried root to a mason or glass jar, then cover completely with your pre-measured vodka.
Cap tightly and shake well. Don’t forget to label your tincture!
