How does it work?
There isn't enough information available to know how club moss works.
Insufficient Evidence to Rate Effectiveness for...
- Bladder disorders.
- Kidney disorders.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Slow heart rate (bradycardia): Club moss might slow down the heart beat. This could be a problem in people who already have a slow heart rate.
Gastrointestinal tract blockage: Club moss might cause “congestion” in the intestines. This might cause problems in people who have a blockage in their intestines.
Ulcers: Club moss might increase secretions in the stomach and intestines. There is concern that this could worsen ulcers.
Lung conditions: Club moss 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 club moss might increase the risk of seizures.
Urinary tract obstruction: Club moss might increase secretions in the urinary tract. There is concern that this could worsen urinary obstruction.
Drying medications (Anticholinergic drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Club moss might increase levels of certain chemicals in the body that work in the brain, heart, and elsewhere. Some drying medications called "anticholinergic drugs" can also these same chemicals, but in a different way. These drying medications might decrease the effects of club moss and club moss might decrease the effects of drying medications.
Some of these drying medications include atropine, scopolamine, some medications used for allergies (antihistamines), and some medications used for depression (antidepressants).
Medications for Alzheimer's disease (Acetylcholinesterase (AChE) inhibitors)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Club moss might increase certain chemicals in the brain, heart, and elsewhere in the body. Some medications used for Alzheimer's disease also affect these chemicals. Taking club moss along with medications for Alzheimer's disease might increase effects and side effects of medications used for Alzheimer's disease.
Various medications used for glaucoma, Alzheimer's disease, and other conditions (Cholinergic drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Club moss might increase certain chemicals in the brain, heart, and elsewhere in the body. Some medications used for glaucoma, Alzheimer's disease, and other conditions also affect these chemicals. Taking club moss with these medications might increase the chance of side effects.
Some of these medications used for glaucoma, Alzheimer's disease, and other conditions include pilocarpine (Pilocar and others), donepezil (Aricept), tacrine (Cognex), and others.
The appropriate dose of club moss depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for club moss. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
