Composition powder is made from Bayberry Bark, Ginger root, White Pine Bark, Cloves and Cayenne. As far as the tea I soaked my mothers in, there is a similar product at Wish Garden Herbs which helps with healing. Go to http://www.wishgardenherbs.com
Click on Pregnancy. Then click on Labor & Delivery - it is called 'After Birth Sitz'. This is a good formula to use as a sitz bath to help with healing and to tighten up any hemorrhoids which might have developed from the pregnancy or birth.
This is a wonderful, exciting time for you and I wish you all the best with your delivery and the new little miracle in your life.
