Astra C

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.

Astra C blends the classic Chinese Jade Screen formula (Yu Ping Feng San) with Western immune nutrients for a holistic approach to prevention. Astragalus and Bai-Zhu Atractylodes build qi, fortify the lungs, and reduce dampness and sweating. Vitamin C and zinc further support immune defense, antioxidant activity, and mucosal barrier protection.

This synergy makes Astra C a reliable daily supplement for those with chronic respiratory sensitivity, allergies, or a tendency to get sick frequently — especially during seasonal transitions or times of stress.

Choose Astra C if you feel vulnerable to colds or flu, deal with frequent sinus or respiratory issues, or have allergic rhinitis that worsens with exposure to pollen, dust, or wind.

It’s also a helpful long-term immune support for individuals recovering from illness or managing stress-related immune weakness. Can be taken preventively or during early onset of symptoms, and is safe for children with appropriate dosage.
