Does milo help to boost milk supply?

A lot of lactating mothers swear by Milo (Australian recipe ONLY). It is said to help boost milk supply. The main ingredient in Milo is malt extract. Barley is also said to be lactogenic. Everyone has their own milk booster and killers, so it's not one for all. http://lactogenicdiet.blogspot.sg/2011/10/malt-as-galactagogue-brief-history.html
