3,4,3',4'-hydroxyl-benzopyranol[5,4,3-c,d,e]benzopyrn-6-6'-dione, Acide Ellagique, Ácido Elágico.
Ellagic acid is a naturally occurring substance. The best sources of ellagic acid in the diet are strawberries, raspberries, blackberries, and walnuts.
Medicinally, ellagic acid is used to prevent cancer and treat viral and bacterial infections.
How does it work?
Ellagic acid may bind to chemicals that cause cancer, and it may also prevent the growth of cancer cells. However, ellagic acid is poorly absorbed and is also eliminated quickly from the body. These characteristics may limit its usefulness as a medicine.
Insufficient Evidence to Rate Effectiveness for...
- Preventing cancer.
- Treating viral infections.
- Treating bacterial infections.
- 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).
The appropriate dose of ellagic acid 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 ellagic acid. 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.
