Rehmannia Eight Combination is built on a precise 3-3-2 structure: three Yin tonics, three moving and draining herbs, and two warming Yang herbs. This balance allows the formula to tonify without cloying and warm without drying.
Rehmannia Eight Combination contains several potent Chinese herbs, including warming Yang tonics (notably prepared Aconite root) and Yin-nourishing herbs with known cardiovascular, renal, and endocrine activity. Because herb-drug interaction research in dogs and cats is limited, pets taking prescription medications should use this formula under veterinary supervision. Avoid use in animals with acute renal inflammation.
Extra caution may be appropriate for pets receiving cardiac medications, diuretics, urinary medications, thyroid medications, medications for blood sugar regulation, or multiple prescription medications. Your veterinarian can determine whether Rehmannia Eight Combination is appropriate based on your pet's condition, medications, and laboratory results.

In Traditional Chinese Veterinary Medicine, Rehmannia Eight Combination (Ba Wei Di Huang Wan) is a classical formula traditionally used to nourish Kidney Qi, Yin, and Yang and warm the Lower Burner. It is indicated for patterns of Kidney deficiency with Cold in the Lower Burner, commonly used to support renal health, healthy urinary function, endocrine balance, and vitality in dogs and cats.
Rehmannia Eight Combination is available in liquid extract (1 oz, 4 oz, or 8 oz) or 500mg tablets (60, 120, or 300 count). Liquid can be mixed into food or administered directly; tablets can be given directly or hidden in food. Dosing varies by species and body weight - your authorizing veterinarian will provide specific guidance.
Results vary by individual and the severity of the pattern. Some animals may show improvement in energy and urinary comfort relatively quickly, while those with more chronic or established Kidney deficiency patterns may require several weeks to months of consistent use. Your authorizing veterinarian can help set appropriate expectations based on your pet's TCVM diagnosis.
Always consult your veterinarian before combining Rehmannia Eight Combination with other medications or supplements. Your authorizing veterinarian will monitor for potential interactions through routine lab work and diagnostic testing. Key interactions to discuss include cardiac medications, diuretics, thyroid medications, and blood sugar medications. See the Potential Drug Interactions section above for details.
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.
Thank you for supporting Traditional Chinese Veterinary Medicine!
