Re: medication

Doesn't sound like your actually taking a medication.
Medication is another more acceptable way of saying drug.
People are more easily convinced to take medications than drugs.
Medications are drugs.
Drugs are poison to our body.

An acupuncturist wouldn't ask you to take a poison.
So being that it is natural stuff, it has to be some kind of vitamin or herb.

During the Master-Cleanse you don't want to take anything in addition to what is laid out for the cleanse. It specifically mentions not to take vitamins.
The reason for this is because it interferes with the ability of the body to go into cleansing mode.
You don't want to interfere with this if you want to get the most cleansing done. The most bang for your buck.

Check with the acupuncturist. it seams that you should easily be able to take a break from them to do a Master Cleanse.
Your acupuncturist should be pleased that you want to do something this healthy for the body.
