Active Ingredient TCVM Actions
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.
- Shu Di Huang (Rehmannia glutinosa, prepared), Prepared Rehmannia Root: The chief herb; nourishes Kidney Yin and Blood with an overall warming effect; the primary Yin tonic in this formula
- Shan Yao (Dioscorea opposita), Chinese Yam Rhizome: Tonifies Spleen, Lung, and Kidney Qi; astringes Essence to help avoid dryness in the Kidneys, Lung, and Middle Burner
- Shan Zhu Yu (Cornus officinalis), Asiatic Cornelian Cherry: Nourishes Liver Blood and Yin, warms and astringes Kidney Essence leakage, and supports healthy urinary function
- Fu Ling (Poria cocos), Poria: Provides gentle Spleen support and leaches Damp from the Middle Burner where Shan Yao acts; balances the cloying effect of the Yin tonics
- Ze Xie (Alisma plantago-aquatica), Asian Water Plantain Rhizome: Promotes urination, drains Damp from the Lower Burner, and assists the Bladder in water transportation
- Mu Dan Pi (Paeonia suffruticosa, root bark), Tree Peony Root Bark: Clears Heat accumulating in the Liver secondary to stasis; balances the warming action of Rou Gui and Zhi Fu Zi
- Rou Gui (Cinnamomum cassia, bark), Chinese Cinnamon Bark: Warms Kidney Yang, disperses Cold in the Lower Burner, and assists the Bladder in water transportation
- Zhi Fu Zi (Aconitum carmichaelii, prepared), Prepared Aconite Root: Strongly warms Kidney Yang and dispels Cold in the Lower Burner; prepared form is used to reduce toxicity while preserving warming action
Potential Drug Interactions
Rehmannia Eight Combination contains 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, blood sugar regulation medications, or multiple prescription medications. Your veterinarian can determine whether Rehmannia Eight Combination is appropriate based on your pet's condition, medications, and laboratory results.
