Are there effective alternative therapies for severe vomiting from pregnancy?

Some alternatives: There are a variety of things including dietary changes, biofeedback, accupuncture, otc emetrol, vit b6 which may help. I usually suggest a brat diet (bread, rice, applesauce, tea and toast) and ask patients to remain sitting up for 30-60 minutes after a meal and eat 6-8 small snack like meals a day because of reflux. Keeping a food diary and noting what you keep down helps too.

May try herbal teas: You can try ginger, raspberry leaf, chamomile or some of the mint family teas. If you use ginger, grate about a teaspoon of ginger and place it in a tea ball. Add boiling water and cover for 10 minutes. You can add a bit of lemon and honey if you like. Ginger ale. Or you can freeze the teas in ice cube trays and suck on them as needed. Eat small frequent meals, eat complex carbs. Avoid odors.
