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.

Colds stopped completely

I gave this to my son, who battled a series of colds, flus, and strep throat in his first term at UCLA. Since he began using this product, he hasn’t fallen ill at all. If he feels anything coming on, he simply increases his intake and it appears to halt the cold in its tracks.

It strengthens the immune system remarkably well! It helped me and my children immensely; we really experienced no colds! Astragalus contains numerous trace elements and essential vitamins needed for humans, making it a valuable supplement.

It works! I take several capsules at the first sign of a cold, and it truly helps prevent illness. I recommend combining it with zinc and grapefruit seed extract for an enhanced anti-cold effect.

Prevents early cold
Accepted by the whole family at the initial signs of a cold. The key is not to overlook these signs, as the illness diminishes. An excellent working astragalus.

Long history for cold
2 people found this helpful
Astragalus is a regular purchase for us. Our whole family uses it (for the children, I opt for a different brand) at the first signs of a cold, combined with vitamin C, echinacea, zinc, and others. It's a truly effective remedy and relatively affordable. Known for over two thousand years in China, astragalus is considered one of the fifty essential herbs in their traditional medicine, believed to improve various body systems and alleviate diseases, although European doctors cite a lack of specific supporting studies. Notably, astragalus can lower blood pressure and should be avoided by pregnant or breastfeeding women, and those with autoimmune conditions should consult a doctor beforehand.

Fewer colds
After taking a combination of 500mg of astragalus and 500mg of quercetin, recommended by my sister, I've experienced fewer colds over the past seven years after suffering from recurrent bronchitis and pneumonia. I chose "Now" products due to their good reputation.

Reduced illness severity
I take 2 capsules three times a day when I have a cold, and it helps prevent me from getting very ill. I recommend it to my family too. My mum says it has helped regulate her blood pressure.
