I am looking for the formula of a commonly used wart treatment
(liquid) that coumpouning pharmacists make for doctors.  It has many
names, but is commonly called verrusol or verisol.  It contains
cantharidin, podphyllin, tincture of benzion, flexible collodian and
salicyllic acid.  Some of my spellings may be incorrect.  I need to
know the exact percentages of every ingrediaent.  Perhaps thsy can be
obtained by asking a compounding pharmacist directly, or posted
online, or in an old directory/textbook of formulas used by
compounding pharmacists.  I just am not having any luck.
Please help.
thanks,
Dr. Crutchfield
ps try a google or other search of 'verrusol'

Hello,

   Since this product (Verrusol) is no longer manufactured, it is
unlikely we can find the exact formula. I have located a pharmacy that
can compound it for you, with a doctor's prescription, for around $20
per ounce. The pharmacist told me it is a very strong product and for
that reason it is no longer around. He said only salicylic acid
solutions of 17% can be bought without a prescription.

Would this information be useful to you?

Regards, Crabcakes

Please take a look at Duke Production Pharmacy Compounds page.

Thanks.
I really need the exact formula.  I am a doctor and use it on a
regular basis.  I obtain it from a coumpounding pharmacist.  They will
tell me what is in it, but will not give the exact formula, via per
centages. They are very secretive in this respect.
With the exception of tincture of benzoin %, which some pharmacisits
include to make it a brown color, I think Bobbie has come very close.
Bobbie, if you can obtain the tinctue of benzoin % great, if not, consider solved.
Thanks for your help, too crabckes.
Thanks,
Dr. C
thanks

Dear Dr. Crutchfield,

Thank you for accepting my findings as the official answer to your question.
(I searched for the tincture of benzoin percentage without any luck.)

I am reposting the information below for your convenience.

Great job, Bobbie!

Thanks crabcakes!  I hope it's the same product as Verrusol.
