Herb Lore's Pregnancy Tea and Pregnancy Tea Plus are healthful and refreshing herbal combinations that are supportive and toning to the entire system before, during and after pregnancy. The regular Pregnancy Tea may be used throughout the entire pregnancy, and because of its high vitamin and mineral content, achieves its best results when used on a long-term, daily basis. Pregnancy Tea Plus is similar to Pregnancy Tea, with the addition of Partridge Berry, a late-pregnancy tonic which further helps to strengthen and nourish the uterus, preparing it for the upcoming work of labor and birth. Because this herb has some very slight oxytocic properties to it (meaning it has the potential to start uterine contractions, although it's not likely), it's recommended for use during the last six weeks of pregnancy only. (The regular Pregnancy Tea may be taken throughout the entire pregnancy however.)
