Kan Essentials Glehnia and Rehmannia Combination 

Veterinary Authorization Required


Glehnia and Rehmannia Combination (Yi Guan Jian) was first published as One Linking Decoction (Yi Guan Jian) in The Continuation of Famous Physician’s Cases Organized by Categories, written by Wei Zhi-Xiu in 1770. The phrase “One Linking” refers to the formulas ability to deal with a variety of disparate patterns, all stemming from the single diagnosis of Liver Blood and Yin deficiency with Qi stagnation. The structure of Glehnia and Rehmannia Combination is relatively simple. Lycium fruit and Dong quai root nourish Liver Blood while raw Rehmannia root clears Empty Heat. Raw Rehmannia root also ensures adequate Kidney Yin. Glehnia root moistens the Stomach Yin, and Ophiopogon tuber moistens the Lung Yin when they have become injured by the combined effects of stasis Heat and Empty Heat. Melia fruit is the sole bitter element among all the sweet-tasting tonics. It serves to regulate stagnant Liver Qi, and also ensures the formula is not too cloying to a compromised Middle Burner.

Ask a Question
  • Could this help an 8 year old cat with kidney disease and hyperthyroidism ? My cat didn’t tolerate his hyperthyroid medication (Methimazole) well so we had to take him off of it . He’s been off of it for a month now and is doing well. He gets subQ fluids 2-3x/wk and is on a kidney diet.

    Thank you for your question! It's great to hear your cat is doing well! Glehnia and Rehmannia Combination is mainly recommended for pets with Liver blood and Yin deficiency. Other herbal formulas made by Kan that help with didney issues and hyperthyroidism are Rehmannia Eight Combination, Spleen Support Formula, and APR Nourishing Formula. It's possible one of these other formulas may be more appropriate for your cat's situation. Please check with your holistic vet to see what they recommend. They will be able to recommend the right formula for your situation. When you're ready to request authorization to purchase, please fill out this form. Thank you for your interest in Chinese herbs!

  • Can this be used with other products, like a calm chew? This would be for a 1yr old, hyperactive shelter rescue with possible separation issues.
