Calculus Bovis

Also known by aliases such as Rhinoceros Gallstone (Xihuang), Ugly Treasure (Choubao), or Natural Calculus Bovis, this traditional Chinese medicine ingredient holds a significant place in healing practices.

Calculus Bovis, a traditional Chinese medicine ingredient

Nature and Flavor: Sweet (Gan) and Cool (Liang).
Meridian Tropism: Primarily enters the Heart (Xin) and Liver (Gan) meridians (channels).
Medicinal Part: Calculus Bovis is obtained during the slaughter of cattle. If found, the gallstone is carefully removed, separated from the surrounding bile, cleaned of any external membrane, and then air-dried in the shade.
Appearance and Characteristics: This substance typically appears in various shapes such as ovoid, spherical, triangular, or quadrangular, varying in size from 0.6 to 3 (sometimes up to 4.5) centimeters in diameter. Some pieces may be tubular or fragmented. Its surface ranges from yellowish-red to brownish-yellow, occasionally covered with a thin, glossy black film, traditionally known as "Wujinyi" (black gold coat). Other surfaces may be rough with wart-like protrusions or exhibit fine cracks. It is light in weight and brittle in texture, easily peeling off in layers. The cross-section is golden yellow, revealing fine, concentric layers, sometimes with a whitish core. It possesses a distinct, pleasant aroma, a bitter taste followed by a sweet and cooling sensation, crumbles easily when chewed, and does not stick to the teeth.

Dosage and Administration of Calculus Bovis

Internal Use: Typically, a dosage of 0.15 to 0.35 grams is recommended, often incorporated into pills or powdered formulations.
External Use: An appropriate amount can be ground into a fine powder and applied to the affected area.

Functions and Actions of Calculus Bovis

Key Functions: It excels at clearing heat and detoxifying the body. Primary Indications: Calculus Bovis is used for conditions such as delirium during febrile diseases, phlegm-induced confusion in stroke, convulsions and spasms, epileptic mania, swollen and sore throat, mouth sores, and various boils, carbuncles, and toxic sores.

Pharmacological Actions:

  1. Effects on the Central Nervous System: Calculus Bovis has demonstrated an ability to counteract central excitatory symptoms induced by substances like caffeine, camphor, and picrotoxin in mice. It also enhances the sedative-hypnotic effects of chloral hydrate, urethane, morphine, or sodium barbiturate. Taurine, a key component of Calculus Bovis, exhibits central inhibitory effects, reducing spontaneous activity and wheel-running in mice, and augmenting the hypnotic effect of sub-threshold doses of pentobarbital sodium. Furthermore, Calculus Bovis possesses anticonvulsant properties, and taurine has shown significant analgesic effects.
  2. Antipyretic Effects: While it does not lower the body temperature of normal rats, Calculus Bovis can inhibit fever induced by 2,4-dinitrophenol and reduce the body temperature of rats with yeast-induced fever.
  3. Effects on the Cardiovascular System: Both Calculus Bovis and its components, bile acids and bilirubin, exhibit cardiotonic (heart-strengthening) effects on isolated frog hearts, guinea pig, or rabbit hearts. Additionally, this substance is known for its choleretic (bile-promoting), hepatoprotective (liver-protective), and anti-inflammatory actions.

Contraindications of Calculus Bovis

Important Safety Note: Pregnant women should use this herb with extreme caution or avoid it entirely.

  • As noted in Ben Cao Jing Ji Zhu (Collected Annotations on the Classic of Materia Medica), "Ginseng acts as its envoy. It is incompatible with Dragon Bone, Rehmannia, Gentian, and Blatta. It is antagonistic to Achyranthes."
  • From Yao Xing Lun (Treatise on the Nature of Medicinals), "It is incompatible with Changshan. It is antagonistic to Dry Lacquer."
  • Pin Hui Jing Yao (Essentials of the Collected Materia Medica) states, "Pregnant women should not take it."
  • Ben Cao Jing Shu (Commentary on the Classic of Materia Medica) warns, "It should not be used by those with diarrhea due to lactation issues or those with spleen and stomach deficiency cold."

Toxicity and Antidotes for Calculus Bovis

Crucial Safety Warning: Excessive use of Calculus Bovis can lead to toxicity. Symptoms may include increased gastrointestinal activity, diarrhea, increased skeletal muscle activity, twitching, and spasms, which can progress to severe suppression. Blood pressure may drop, arrhythmias can occur, and there may be a reduction in red blood cells and hemoglobin. In severe cases, patients may enter a semi-comatose or comatose state, ultimately leading to death from respiratory and circulatory failure. Always adhere strictly to prescribed dosages and consult a qualified TCM practitioner or healthcare professional before using Calculus Bovis to avoid adverse effects.

Antidotal Measures:

  1. In early stages, induce vomiting and perform gastric lavage, followed by the administration of a general antidote.
  2. Administer central nervous system stimulants to counteract central depression.
  3. For hypotension (low blood pressure), pressor agents can be added to intravenous fluids.
  4. For severe abdominal pain and diarrhea, oral belladonna tablets or subcutaneous atropine sulfate injections can be given, with repeated applications if necessary.
  5. Taurine, a component of Calculus Bovis, has a stimulating effect on the heart and a mild vasodilating effect. To prevent arrhythmias, reserpine can be administered via intramuscular injection or orally as a prophylactic measure.
  6. Other symptomatic treatments should be applied as needed.

Formulation Compatibility of Calculus Bovis

  1. For acute febrile diseases and pediatric convulsions with high fever, delirium, and spasms: Calculus Bovis cools the Heart, clears the Liver, and has anticonvulsant and tranquilizing effects. It is often combined with Cinnabar (Zhusha), Whole Scorpion (Quanxie), and Uncaria (Gouteng), as seen in formulas like Niuhuang San (Calculus Bovis Powder).
  2. For febrile diseases where heat invades the pericardium, stroke, convulsions, and pain due to phlegm-heat obstructing the Heart orifices, leading to altered consciousness, locked jaw, and phlegm-sound in the throat: This herb clears Heart heat, transforms phlegm, opens the orifices, and revives consciousness. Used alone as a powder dissolved in bamboo juice can be effective, as in the formula from Waitai Miyao (Arcane Essentials from the Imperial Library) for infant locked jaw. It is also combined with Musk (Shexiang), Gardenia (Zhizi), and Coptis (Huanglian) to collectively clear heat, transform phlegm, open orifices, and revive consciousness, such as in the famous Angong Niuhuang Wan (An Gong Niu Huang Wan).
  3. For swollen, ulcerated throat, carbuncles, boils, and other conditions due to stagnant heat and toxins: Calculus Bovis is a potent heat-clearing and detoxifying agent. For swollen and sore throat and mouth sores, it is often combined with Scutellaria (Huangqin), Realgar (Xionghuang), and Rhubarb (Dahuang), as in Niuhuang Jiedu Wan (Calculus Bovis Detoxifying Pill). For swollen and ulcerated throat, it can be powdered with Pearl (Zhenzhu) and blown into the throat, as in Zhuhuang San (Pearl and Calculus Bovis Powder). For carbuncles, boils, breast cancer, and scrofula, it is combined with Musk (Shexiang), Frankincense (Ruxiang), and Myrrh (Moyao) to clear heat, detoxify, invigorate blood, and disperse stagnation, as in Xihuang Wan (Rhinoceros Gallstone Pill).
  4. For high fever with restlessness, delirium, and epileptic convulsions: Delirium and convulsions are often caused by high fever or phlegm-heat obstructing the clear orifices. Calculus Bovis clears Heart heat and dispels turbid phlegm, achieving effects of opening orifices and calming convulsions. Clinically, it is often formulated into pills or powders with heat-clearing and orifice-opening herbs such as Coptis (Huanglian), Scutellaria (Huangqin), Gardenia (Shanzhi), and Musk (Shexiang), used for severe heat-induced coma and convulsions.
  5. For ulcerated throat, various heat-toxic sores, and carbuncles: Calculus Bovis is a vital herb for clearing heat and detoxifying. It is applicable for throat swelling and pain, sores, and various surgical conditions categorized as "yang" patterns caused by heat toxins. It is often combined with Indigo Naturalis (Qingdai) and Borneol (Bingpian) for throat pain; and with Honeysuckle Flower (Jinyinhua), Paris polyphylla (Qiyeyizhihua), and Licorice (Gancao) for boils and sores.
  6. Specific Combinations: When combined with Musk (Shexiang), Arisaema with Bile (Tianzhuhuang), Whole Scorpion (Quanxie), and Uncaria (Gouteng), it strongly transforms phlegm, opens orifices, clears heat, and calms spasms. With Coptis (Huanglian), Scutellaria (Huangqin), Gardenia (Zhizi), Turmeric Tuber (Yujin), and Cinnabar (Zhusha), it clears heat, detoxifies, opens orifices, and tranquilizes the spirit. When paired with Indigo Naturalis (Qingdai), Pearl (Zhenzhu), Human Fingernail (Renzhijia), Elephant Tusk Shavings (Xiangyaxie), and Borneol (Bingpian), it clears heat, detoxifies, reduces swelling, and alleviates pain.
