Citricidal is a brand-name supplement, based on a component found in grapefruit pulp and seeds. Known as an antimicrobial compound, the seeds and pulp of grapefruit have a variety of properties, including use as a fungicide, antiviral and broad-spectrum, bacteria-fighting capabilities. Generally known for its low toxicity levels and safety, grapefruit seed extract is commonly purchased from drug stores and health food stores for its therapeutic antioxidant effects, to preserve cosmetics and foods, and in animal feed to help prevent parasites and mold, as well as a disinfectant for fish and poultry. However, as with anything, too much of a good thing can be bad for you. Some drug interactions are cautioned.
Beware of potential drug interactions of prescribed medications and grapefruit seed extract. For example, some patients undergoing treatment for blood clotting issues who have been prescribed blood thinners such as warfarin may experience an increase in international normalized ratio blood test (INR), which defines the effectiveness of such medications to prevent blood clots while at the same time reducing the risk of uncontrolled bleeds in patients.
If you're taking immunosupressants, antihistamines or drugs or medications that lower cholesterol, avoid taking grapefruit seed extract or Citricidal as it may interfere with the function of the medication.
Take grapefruit seed extract as directed on bottle, as taking too much may kill the good bacteria in your digestive tract responsible for breaking down and digesting the contents of your stomach and intestines. Too much Citricidal or grapefruit seed extract in the system can destroy this bacteria, leading to inability of the digestive tract to function properly absorb nutrients, and may even lead to irritable bowel conditions that cause nausea and diarrhea.
Pregnant women or those breastfeeding should not take Citricidal without first discussing its use with their doctor or pediatrician. In addition, people with bleeding disorders or conditions that require the use of blood thinners should not use Citricidal before any type of dental work or surgery, as it may prevent blood from clotting properly. You should stop using Citridical for at least two weeks before any such situations and to discuss potential or harmful side effects with your physician or health care provider.
