Germander is a plant. The parts that grow above the ground are used to make medicine.
Despite serious safety concerns, people take germander for treating gallbladder conditions, fever, stomachaches, and mild diarrhea; as a digestive aid, germ-killer, and “rinse for gout;” and to help with weight loss.
Some people use germander as a mouthwash to freshen the breath and kill germs in the mouth.
In manufacturing, germander is used as a flavoring in alcoholic beverages.
How does it work?
There isn't enough information to know how germander might work.
Insufficient Evidence to Rate Effectiveness for...
- Gallbladder conditions.
- Weight loss.
- Use as a germ-killer (antiseptic).
- Use as a mouthwash.
- 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).
Germander is UNSAFE. France has banned its sale. Canada does not allow germander to be included in products that are taken by mouth. However, the US still allows germander to be used in small amounts as a flavoring agent in alcoholic beverages.
The safety concern is that germander has caused several cases of liver disease (hepatitis) and death.
Pregnancy and breast-feeding: Germander is UNSAFE for anyone to take as medicine. If you take it while pregnant or breast-feeding, you will endanger yourself as well as your baby.
The appropriate dose of germander 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 germander. 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.
