What It Supports
- Blood invigoration and cardiovascular support: Invigorates Blood stasis in the Upper Burner and opens the vessels and channels to support a healthy cardiovascular system and address lower limbs, ear tips, and paws that are cool to the touch
- Liver Qi regulation and emotional wellbeing: Regulates Liver Qi and nourishes Liver Blood to address occasional irritability, depression, agitation, timidity, noise sensitivity, territoriality, and occasional anxiety
- Sleep and vitality support: Addresses restless sleep, fatigue, lethargy, and occasional palpitations associated with Liver Blood deficiency and Blood stasis in the Upper Burner
- Skin, coat, and liver support: Addresses dry skin, hair, coat, dry eyes, and occasional itch associated with Liver Blood deficiency; supports healthy liver enzyme levels
TCVM Principles
- Primary action: Invigorates Blood, nourishes Liver Blood, opens and unblocks the vessels and channels, and regulates Liver Qi
- Pattern addressed: Liver Blood deficiency, Liver Qi stagnation, and Blood stasis in the Upper Burner; when stronger Blood-moving action is required, Dispel Stasis in the Palace of Blood (Jia Wei Xue Fu Zhu Yu Tang) may be more appropriate - consult your TCVM veterinarian to confirm the appropriate pattern diagnosis; avoid use during pregnancy or with typical Dampness symptoms
- Approach: Built on two classical sub-formulas - Si Ni San (Four Cold Extremities Formula, ca. 500 A.D.) for Liver Qi-moving (Chai Hu, Chi Shao, Chao Zhi Ke, Gan Cao) and Si Wu Tang (Four Substances, 1742) for Blood tonification (Sheng Di Huang substituted for Shu Di Huang to cool Blood, Chi Shao substituted for Bai Shao to cool and move Blood, Chuan Xiong, Dang Gui Shen) - with Guang Chao Tao Ren and Hong Hua for Blood invigoration, Jie Geng to guide the formula upward, and Chuan Niu Xi to descend Blood out of the Upper Burner

Active Ingredient TCVM Actions
Blood's Palace is built on two classical sub-formulas - Si Ni San for Liver Qi-moving and Si Wu Tang for Blood tonification - with deliberate substitutions (Sheng Di Huang for Shu Di Huang, Chi Shao for Bai Shao) to cool Blood and address stasis Heat, plus Peach Seed and Carthamus Flower for Blood invigoration and two channel-guiding herbs to direct the formula's action to the Upper Burner.
- Guang Chao Tao Ren (Prunus persica, dry-fried peeled seed) - Dry-Fried Peeled Peach Seed: Strongly invigorates Blood and dispels Blood stasis; one of the primary Blood-invigorating herbs in this formula
- Dang Gui Shen (Angelica sinensis, root body) - Dong Quai Root Body / Chinese Angelica: Both tonifies and moves Blood; one of the Si Wu Tang core herbs; the root body form emphasizes Blood nourishment while also moving Blood
- Hong Hua (Carthamus tinctorius) - Carthamus Flower / Safflower: Invigorates Blood and dispels Blood stasis; works with Peach Seed as the primary Blood-invigorating pair
- Chuan Niu Xi (Cyathula officinalis) - Cyathula Root / Sichuan Ox-Knee: Eliminates stasis and descends Blood out of the Upper Burner; guides the formula's Blood-moving action downward to prevent stasis from accumulating in the chest
- Sheng Di Huang (Rehmannia glutinosa, raw) - Raw Rehmannia Root: Tonifies Blood and cools Blood; substituted for the prepared Rehmannia root normally used in Si Wu Tang to cool Blood and address stasis Heat; one of the Si Wu Tang core herbs
- Chi Shao (Paeonia lactiflora, red) - Chinese Red Peony Root: Cools Blood, invigorates Blood, and supports Liver Blood; substituted for Chinese white peony root to cool Blood of any stasis Heat; serves dual roles in both the Si Ni San and Si Wu Tang sub-formulas
- Chao Zhi Ke (Citrus aurantium, dry-fried mature fruit) - Dry-Fried Bitter Orange Mature Fruit: Moves Qi internally and addresses stagnation in the chest and abdomen; one of the four Si Ni San herbs; dry-frying moderates its action
- Chuan Xiong (Ligusticum chuanxiong) - Sichuan Lovage Rhizome / Chuanxiong: Invigorates Blood and moves Qi; prevents the Blood tonics from becoming cloying; one of the Si Wu Tang core herbs
- Jie Geng (Platycodon grandiflorum) - Platycodon Root / Balloon Flower Root: Guides the formula upward to the Upper Burner; acts as an envoy herb to direct the formula's Blood-moving action to the chest and upper regions of the body
- Chai Hu (Bupleurum chinense) - Bupleurum Root / Chinese Thoroughwax: Moves stagnant Liver Qi, guides the formula peripherally, and contributes a cooling influence; the primary Liver Qi-moving herb and one of the four Si Ni San herbs
- Gan Cao (Glycyrrhiza uralensis) - Chinese Licorice Root: Harmonizes the formula, works with Chi Shao to relax the sinews and eliminate stagnation, and tonifies Spleen Qi; one of the four Si Ni San herbs
Potential Drug Interactions
Blood's Palace contains several potent Chinese herbs, including Blood-invigorating, Liver Qi-moving, and Blood-cooling herbs with known cardiovascular, hepatic, and anti-inflammatory 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 during pregnancy or with typical Dampness symptoms.
Extra caution may be appropriate for pets receiving anticoagulant or antiplatelet medications, cardiac medications, hepatic medications, NSAIDs, or multiple prescription medications. Your veterinarian can determine whether Blood's Palace is appropriate based on your pet's condition, medications, and laboratory results.
