Astragalus-root shows mixed effects
Effects of Chinese herbal medicine and cold exposure on plasma glucose, leucine and energy metabolism in sheep.
Study on herbal effects limited
We conducted an experiment to evaluate the effects of a traditional Chinese herbal medicine mixture, including astragalus-root, when sheep were exposed to cold temperatures. The study involved feeding four sheep either a mixed hay diet or hay supplemented with 2% of the herbal mix over two periods, during which they experienced a controlled cold exposure for five days.
While we observed some benefits of the herbal treatment, specifically regarding nitrogen balance and energy metabolism, the results showed that the metabolism of plasma leucine—important for protein synthesis—remained unchanged in cold conditions. Although plasma glucose and energy metabolism improved with both the herbal diet and cold exposure, the herbal mixture alone did not significantly enhance the sheep's ability to cope with cold stress in terms of leucine metabolism.
Overall, while astragalus-root mixed with other herbs seems beneficial for certain metabolic processes, it did not provide clear advantages in terms of cold adaptation for the sheep in our study.

Cold symptoms gone
Remarkably, it flushed everything out of me the second night. I bought this to boost my immune system during flu season as I don’t take flu shots. After catching a cold, I took this with Carlson Zinc and Vitamin C, alongside Astragalus twice daily. The cold hit hard (stuffy head, sore throat), but it had vanished within two days! I was up and clearing my nose and coughing everything out the second night. By the third day, I merely had a few sneezes. No antihistamines or cough syrup, just one cough drop and some tea! Amazing! Additionally, an itch from menopause is gone! I will definitely keep this in my homeopathic arsenal!

No colds anymore
Improved immunity! I worked in education for 25 years and have always caught back-to-back colds during winter months, but not anymore! Now, I just take one of these daily with my vitamins, and it has made a huge difference. I’m not a “supplement person,” but these have been a game changer for me.

No more colds
Improved health since starting it. No adverse reaction, and I haven't had a cold since I began taking it two months ago. Previously, I had several colds in 2013.

Flu-free family
This stuff works! My family hasn't been sick with a cold or flu for over a year since we began taking it!

Less severe colds
Has really boosted my immune system. I'm on my third or fourth bottle of this specific brand of Astragalus and it truly seems effective. I take one capsule nightly as a preventative measure for my immunity and have noticed I've been getting sick less often with colds and infections. When I do catch a cold, I increase the dosage to at least twice a day, and my colds usually diminish in severity swiftly afterwards.
