It is in fact an ingredient of volufiline.  I think the other half was a compound from nutmeg, macelignan.  I haven't heard of its use in NBE outside of volufiline, but as a source of saponins it's not surprising that it might work.  Similar to other sources you might try an extract standardized to ##% saponins (e.g., 10-50%, or whatever), or a 10:1 extract or etc.  Then experiment with that and see if it does anything.  A 1:1 extract like you might sometimes find is likely to be too weak.
