Astragalus together with Echinacea are good herbal remedies during the cold season as both of them make the immune system stronger. You can buy ready-to-use tinctures containing the two of these herbs.

Astragalus is considered by Chinese practitioners as the primary herb for diabetes. In the US the primary herb for diabetes is considered to be the cedar berry as opposed to the juniper berry. Unfortunately there is little information on both alternatives for diabetes, other than anecdotal information. However, we do know that both are sacred in their respective cultures.
The Native Americans valued the cedar berry highly, and the Chinese have successfully used astragalus going back hundreds of years.

I too have used astragalus for myself, and my yorkie, who lived a good long life (17 years). Also the stray cat, I sprinkle about a half tsp. on his food once a day whenever he's sick. It's been very healing for him.
