1.0 About Quercetin

What is Quercetin  
 
Quercetin sometimes called nature’s Benadryl, is a naturally occurring flavonoid found in many plants. Flavonoids (or bioflavonoids) are plant-pigments that play an essential role in attracting pollinators to plants. Flavonoids also offer a host of beneficial properties to humans, dogs, cats and other animals. Quercetin is:
  • Anti-allergenic
  • Anti-carcinogenic
  • Anti-fungal
  • Anti-Inflammatory
  • Anti-microbial
  • Anti-viral
Quercetin rich foods and herbs for dogs
Examples of quercetin-rich fruit, vegetables and herbs:
  • Apples (fresh)
  • Berries
  • Bananas
  • Broccoli
  • Cherries (dark)
  • Garlic (fresh)
  • Grapefruit (particularly white grapefruit) and grapefruit seed extract
  • Green tea
  • Ginkgo biloba
  • Chamomile tea
  • Parsley
  • Summer squash
  • St. John’s Wort
Quercetin can be used in various forms:
Capsules
Drops

As quercetin can sometimes be difficult for the body to assimilate, taking Bromelain (pineapple derived digestive enzyme) with quercetin can add absorption.
  • Bromelain also works to inhibit histamine.
  • The ratio is: 1/4 to 1/3 the amount of bromelain to quercetin.
