Description
- Astra C is ideal for those who seem to catch every cold going around, suffer from seasonal allergies, or experience spontaneous sweating and sensitivity to wind. This formula strengthens your body’s outer defenses (wei qi), helping you stay resilient against illness, irritation, and allergic flare-ups.
- In Traditional Chinese Medicine (TCM), this pattern often reflects weak defensive qi — your first layer of protection against external pathogens. Astra C combines time-tested immune tonics with vitamin C and zinc to reinforce the surface, calm allergic responses, and reduce your susceptibility to colds, flu, and respiratory distress.
