Clubmoss

Background

Clubmoss is an herb. People use the whole plant to make medicine.

People use clubmoss for bladder and kidney disorders, and as a diuretic to increase urine, but there is no good scientific evidence to support these uses. Using clubmoss might also be unsafe.

Don't confuse clubmoss with Chinese club moss or fir club moss. Chinese club moss and fir club moss contain a chemical called huperzine A. Clubmoss does not contain this chemical.
When taken by mouth: Clubmoss is POSSIBLY UNSAFE because it contains several poisonous chemicals. However, so far, no poisonings have been reported.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Clubmoss is POSSIBLY UNSAFE for anyone, including pregnant and breast-feeding women. Don't use it.

Slow heart rate (bradycardia): Clubmoss might slow down the heartbeat. This could be a problem in people who already have a slow heart rate.

Gastrointestinal tract blockage: Clubmoss might cause "congestion" in the intestines. This might cause problems in people who have a blockage in their intestines.

Ulcers: Clubmoss might increase secretions in the stomach and intestines. There is concern that this could worsen ulcers.

Lung conditions: Clubmoss might increase fluid secretions in the lung. There is concern that this could worsen lung conditions such as asthma or emphysema.

Seizures: There is concern that clubmoss might increase the risk of seizures.

Urinary tract obstruction: Clubmoss might increase secretions in the urinary tract. There is concern that this could worsen urinary obstruction.
