Goldenseal is suggested to treat common cold, the flu, allergies, stomach problems, chronic fatigue syndrome (CFS), liver problems, boost the immune system and for passing marijuana drug tests.

As well, there are mouth wash formulations for treating gum problems and cream formulations for treating eczema, acne, rash and herpes. Experts believe it has antibacterial and antiviral properties.

It is commonly combined with echinacea in a pill and sold to treat symptoms of the common cold or the flu. Anecdotal reports claim that it can enhance the effects of echinacea.

All the clinical studies used an active ingredient berberine found in goldenseal. To get that amount of the active ingredient by taking goldenseal, you will be taking a ridiculously high dose.

Goldenseal is often marketed to help you pass drug testing.

Beating drug tests for marijuana or other drugs like cocaine can be very difficult (if not impossible). Clinical studies show that taking goldenseal does not mask the fact that you are using marijuana.

Another study showed that even drinking a gallon of water while taking goldenseal compared to just drink the water alone didn't affect the results of the drug test.

The author John Uri Lloyd published a novel titled Stringtown on the Pike that mentioned using this herb.

In clinical studies, there are no side effects reported from using goldenseal or the active ingredients berberine by itself. Avoid using this herb if you are pregnant or breastfeeding your infant.
