Kan Essentials Rehmannia Eight Combination



Rehmannia Eight Combination is the literal translation of Ba Wei Di Huang Wan, also known as Precious Golden Tonify the Qi Pill (Jin Gui Shen Qi Wan). This formula was another lasting contribution of Zhang Zhong-Jing of the Han dynasty, and was first published in about 500 A.D. in Essentials of the Golden Cabinet. Qi is life force, and is generated through the mingling of Yin and Yang; Rehmannia Eight Combination contains tonics for both. The Yang tonics also add warmth to the lower burner, assisting the Bladder in water transportation. The first three herbs are Yin tonics. Prepared Rehmannia root has an overall warming effect and nourishes Kidney Yin and Blood. Chinese yam rhizome astringes Essence, helping to avoid dryness in the Kidneys, Lung and Middle Burner. Asiatic cornelian cherry nourishes Liver Blood and Yin, and helps astringe Kidney Essence leakage.

Poria provides gentle Spleen support and leeches Damp from the Middle Burner where Chinese yam rhizome acts. Tree peony root bark clears Heat accumulating in the Liver, secondary to stasis.

Ask a Question
  • I noticed, on the back of the bottle, it states to evaporate alcohol place drops in hot water. How much hot water? Do I place all 5-10 drops in hot water, let cool, then place in my cat's food? I concerned about the alcohol. My cat has stage 2 kidney disease and will be taking Gabapentin. Is this safe to use with the Gabapentin?

    Thank you for your question!

    We are not aware of any interactions with Gabapentin. However, we recommend checking with your vet to make sure this herbal formula is appropriate for your kitty's situation and medical condition. 

    While the herbal extracts can be given as-is, we recommend the following strategies to make them more palatable. 

    Here are a couple of those strategies: 

    1) Add water or broth to the herbal extract. 

    2) Small doses can be hidden in canned food or ground meat

    3) If your pet takes pills, you can add the herbal extract to a capsule. 

    4) Simmer the extract in a pan on very low heat to evaporate off the alcohol. Initially, the aroma of alcohol will be strong - once it becomes barely detectable, remove the liquid from the heat and replace it in the bottle. Then, refrigerate the bottle.

    We hope these ideas help increase the palatability of herbal extracts for your pet!

  • Is this product safe for a dog with Insulinoma?

    Thank you for your question! While our vets haven't experienced any negative effects of using this product with insulinoma, we recommend checking with your vet who knows your pet's individual case best. If you don't have a vet, we recommend getting a consultation with one of our vets.

  • Is this product safe for a dog in renal failure?

    Thank you for your question! I'm sorry to hear your dog is struggling with renal failure. Rehmannia Eight can help support the kidneys and restore Kidney Yin energy. This product is safe and can be used in renal failure, but we recommend checking with your vet to make sure you're using the appropriate herbal formula for your dog's specific characteristics.

  • What is the dosage per dogs body weight?

    Hi! Thank you for your question!

    Vets usually choose a dose in that range based on individual characteristics, constitution, and symptoms. Dosing and duration depend on the weight of the animal and its condition.

    We recommend you contact your vet as the dosing and duration for the formula can vary from patient to patient.
