3. Echinacea is safe during pregnancy and is also great for regulating the immune system; making it strong enough to fight invaders, yet smart enough to know what to attack and what not to.
4. Vitamin C is an effective natural antihistamine, and you can take up to 2000mg/day. Try to spread 500mg doses throughout the day.
5. A healthy diet of anti-inflammatory foods! Follow The Gentle Birth Method nutritional guidelines for a healthy, glowing pregnancy and better birth.
