The Nat Sulph picture and modalities

Natrum Sulphuricum centres on sensitivity to damp and humidity. The chest can be rattling and worse in the morning, the digestion bilious and liverish with loose morning stools and wind, and the mood low, especially in wet surroundings. The classic teaching also links the remedy with the after-effects of a head injury. A homeopath weighs the damp aggravation, the liver picture, and the constitution together rather than relying on one keynote.

Before you consider Nat Sulph

This is materia-medica information, not advice to self-treat. Asthma, liver complaints, and mood changes after a head injury are all serious matters that need proper medical assessment and treatment, never a remedy alone. In homeopathy the correct remedy and potency are chosen for the whole individual by a qualified practitioner, and the same remedy is not right for everyone. Homeopathy should complement, not replace, conventional care.
