Certain herbs (such as danshen, devil's claw, eleuthero, garlic, ginger, horse chestnut, papain, red clover, and saw palmetto) can also increase the risk of bleeding if combined with ginseng.
* Panax ginseng may affect heart rhythm and can increase potential side effects from theophylline (and similar asthma drugs), albuterol, clonidine and sildenafil citrate (Viagra).
*Panax ginseng may interfere with the metabolism of monoamine oxidase (MOA) inhibitors, such as phenelzine sulfate, tranylcypromine sulfate and isocabaxazid. It's also believed to affect levels of neurotransmitters (chemicals that carry messages from nerve cells to other cells) and may interact with antipsychotic drugs such as chlorpromazine and fluphenazine.
*Panax ginseng stimulates the central nervous system, so it may increase the effects of prescription drugs that do the same (such as medications for attention-deficit hyperactivity disorder, narcolepsy, and obesity). The combination may raise heart rate and blood pressure.
*Panax ginseng has been found to interfere with the metabolism of drugs processed by an enzyme called cyp3A4. Ask your doctor to check if you are taking medications of this type.
