Hi Robin,
We don't succeed all the time with these cases, but probably most. Often enough that I question the diagnosis on many of them anyway. So, short answer, yes, you could fully expect some success and we would welcome the opportunity to help you. The list of differentials is extensive - Damp Heat, Qi deficiency, Yin deficiency, Qi deficiency leading to Blood stasis, Kidney deficiency... - so do your best with it, but maybe plan on sending the owner out the door with the antioxidants you mention and getting back to us with the particulars so we can recommend a formula she can pick up later. Unless of course it's really obvious to you.
If you do bring it back here, then we can help most if you provide pulse, tongue and point data (which points improved the pulse, and what did you do to achieve that - tonify or sedate?).
Lastly, if there is anyone around who does chiropractic, you might want to arrange that as well.
All the best,
Steve
