You should also be able to find other herbs and supplements at any health food, vitamin store, and some "super" grocery and drug stores.
I recommend you find a source of Fenugreek, which seems to add the most benefit if you can't do PM.. I've been able to find that at two local supplement shops and the "health food" section of a local supermarket. Look in the women's section.
I tried dong quai, which is listed as an ingredient in some breast formulas, but additional research showed no benefit so I dropped that.
Since it can take up to 3 months to really get things going, you may be better off waiting until you're free to get what you need, and just work out your starting program plan while you're waiting.
Check personal programs, and the introduction sections for lists of herbs that will work... Other than PM, I've seen most herbs mentioned available from one or more of the sources I mentioned.
it's also helpful to pop into someone's profile and see if they posted their program, or have a thread with their program in it. (it's not "spying"

)
