Know Your Remedies: Sulphuricum Acidum (Sul-ac.) 1

Common Names: Sulphuric acid; H2SO4.

General Information

Sulphuric Acid is one of the constituents of combustion engine exhausts (cars, planes, diesels, etc) which may explain why so many who need it in potency are also sensitive to smoke, smog, and odours. Other common symptoms include sourness of discharges such as perspiration, eructations (burps), reflux, vomit, and breath, hot flushes during menopause, and tendency to bruises or haemorrhage. The person needing Sul-ac. may also be chilly, complain of internal trembling, and be weak with perspiration. Pains appear gradually but disappear rapidly.


  • Hurried – walk quickly and eat rapidly.
  • Confusion and awkwardness from hurry.
  • Nervous and anxious to get things done.
  • Dissatisfied and irritable.


  • Easy bruising – from the least bump.
  • Useful for bruising when Arnica doesn’t relieve.


  • Painful ulcers that often appear at regular intervals.
  • Heartburn and gastritis (inflammation of the stomach).
  • Craving for brandy.
  • Dislike of water unless alcohol (especially brandy) is added.

Where do I find it?

While above self-limiting or acute complaints are suitable for home treatment, also contact your healthcare provider during emergency situations or if symptoms worsen or fail to improve. Chronic or persistent complaints, which may or may not be mentioned above, require a different treatment and dosage protocol so are best managed by a qualified homeopath for good results.

Dosage Instructions (suitable for babies to adults)

For acute and self-limiting complaints, take one pill or five drops of the remedy every 15 minutes to 4 hours (as often as every 15 minutes for intense symptoms or once every 4 hours for milder ones). Once an improvement is noticed, stop dosing and repeat the remedy only if symptoms return. If there is no improvement at all by three doses, choose a different remedy or seek professional guidance. Chronic symptoms or complaints require a course of professional treatment to manage the changes in potencies and remedies that will be required.
