I went to a dinner once, in the 70s I think. The keynote speaker was Ladean Griffin http://www.goodreads.com/author/show/847184.Ladean_Griffin
She was sharing her experience about her whole family being on a fruitarian diet with the exception hot cereals in the morning. Someone asked her how she managed that diet during her pregnancy and infant care. She said that watermelon was what got her breast milk flowing.
Apparently, it is good to take in more fluids. Watermelon has a lot of water. So, I think more liquid containing foods, like soup and watermelon could help.
It may not be the water. Watermelon is very high in potassium, which is one of the reasons it is so diuretic. Breast milk is also very rich in potassium so it could have something to do with the potassium increasing milk production. Interestingly, fenugreek that also increases breast milk contains around 28mg of potassium per teaspoon of seed. That would be considered a rich potassium source.
A friend of mine with a 2 month old baby is struggling with a dwindling milk supply. The mother has had antibiotics regularly over the last 4-5 months for respiratory infections and then (mostly recently) a UTI and mastitis. She just had an allergic reaction to the most recent antibiotic, and I'm worried about her. Are the Adrenal Tonic herbs safe for a nursing mother?
Yes.
I think she needs to rebuild her immune system. Are the Big 3 (pau d'arco, andographis, and chaparral) okay with nursing?
The andrographis in particular would likely pass in to the milk making it very bitter. Therefore, it is not advised. The Adrenal Tonic has immune boosters as well.
Any suggestions to increase milk supply?
Goat's rue is the most effective, but can be hard to find. Fenugreek is also very effective and is readily available.
Nettle leaf can be used to increase the nutritional value of the milk.
