Aconitum napellus: If a rash breaks out suddenly and the person feels extremely anxious and apprehensive, this remedy may be indicated. Exposure to sunlight, or being out on a cold dry windy day, may precipitate symptoms. The rash may feel numb or itch, and stimulants may reduce the itching.

Belladonna: This remedy is indicated when a feeling of heat accompanies a bright red rash that comes on intensely and suddenly. The person’s face is flushed, and pulsations may be felt in the head or other parts of the body.

Camphora: This remedy can be helpful for a rash that comes from sun exposure (and is sometimes also used in sunstroke). A guiding indication for this remedy is a feeling of general coldness and sensitivity, despite which the person does not want to be covered.

Natrum carbonicum: When this remedy is indicated, a blistery rash comes up in patches, and the person feels tired or ill from being in the sun. A person who needs this remedy also tends to be sensitive to weather changes and allergic to many foods, especially milk.

Natrum muriaticum: A person who needs this remedy may feel tired and weak after being in the sun, developing headaches and a blotchy or hive-like rash that itches and burns. Strong thirst, a craving for salt, and a private or reserved personality are other confirmations for this remedy choice.

Staphysagria: A blistery-looking rash with itching that changes locations from scratching suggests the use of this remedy. Staphysagria is often suited to individuals who are very sensitive emotionally and strongly affected by insults or embarrassment.
