Single Homeopathic Remedy – Hepar sulphuris calcareum

Single Homeopathic Remedy – Hepar sulphuris calcareum
Common Name
Hepar sulph, Calcium Sulfide
Key Characteristics
Hepar sulphuris calcareum is a remedy derived from a combination of calcium carbonate (from oyster shells) and sulfur, heated together to form calcium sulfide.
It is known for its strong affinity for the respiratory system, skin, and areas prone to suppuration (pus formation).
This remedy is characterized by its ability to address conditions involving extreme sensitivity to pain, cold, and touch, often accompanied by irritability or a tendency toward infection.
It is particularly noted for promoting the expulsion of pus or aiding in the healing of abscesses when drainage is needed.
When to Use Hepar sulphuris calcareum for Dogs
Hepar sulphuris calcareum matches dogs that are unusually sensitive — both physically and temperamentally — and may snap or growl when approached due to discomfort, and can be used for:
- Abscesses or Boils
It is ideal when a dog develops painful, pus-filled swellings, such as dental abscesses or skin boils, especially if the area is highly sensitive to touch and the dog reacts strongly to any disturbance.
- Respiratory Infections
Use this remedy for dogs with harsh, croupy coughs or respiratory conditions like kennel cough, particularly when the cough worsens in cold air and the dog seems chilly or irritable.
- Ear Infections
It can help with chronic or acute ear infections where there’s thick, offensive discharge and the dog is hypersensitive to having its ears handled.
- Skin Conditions with Suppuration
Hepar sulph is effective for skin issues like infected wounds or pustules, especially when the infection is slow to resolve and the dog shows signs of discomfort or aggression due to pain.
- Healing after Injury
It is useful in cases where a wound or puncture is at risk of festering, helping to either bring an abscess to a head for drainage or resolve it if caught early.
