What herbs can help boost milk supply?

I have a couple of friends who took Nurturing Remedies Organic Moringa Tea. Feedback from them is that it helps maintain their supply, which seemed to have dropped after returning to work. One of them felt that it was effective in increasing her supply (she took one tea bag a day as suggested). If you are interested in trying, you can get it at http://www.mumsfairy.com/collections/increase-milk/products/remedies-organic-moringa-tea Some other food-related ways to boost supply recommended by most include: - drinking more water - drinking soy milk (but may affect hormonal levels, best to start with small amount first and see if baby has any reaction) - having oatmeal as part of your daily diet - taking fennel and fenugreek supplements - red dates and longan tea - having a well balanced diet with good quality protein and god amount of carbohydrate (mothers who are breastfeeding typically needs an additional 300-500 calories) - green papaya and fish soup Everyone is different and hence it may take some trial and error to find a milk booster suitable for you.
