Whenever I feel like I’m trying to come down with a cold, I have my own remedy that works quite well:
Small amount of water.
Add 2 squirts of colloidal silver
2 squirts of echinacea
2 squirts of elderberry extract
Drink that and take 5 Vitamin C tablets.
If not better within 3-4 hours, I will repeat the above.
It usually works for me after just one dose.
