Chinese herbs and drug testing

[Guest guest]

One of my patients has to go for drug testing at his doctor's office

(new policy of a pain management doctor here in Texas). I am treating

this patient with raw herbs, including Huo Ma Ren (Hemp Seeds) to

moisten his intestines. Now I am concerned that the urine testing

will come back positive. Does anyone know anything about the

pharmacology of Huo Ma Ren. I know the seeds are radiated so they do

not germinate. Materia Medica is not helpful. I waiting what Mayway,

the company I order my raw herbs from has to say.

Any feedback directly to me would be great.

Thanks,

Julia
