Prickly heat, medically known as miliaria, develops when blocked sweat ducts trap perspiration under the skin, producing small, itchy or prickling bumps. It is especially common in hot, humid climates, in infants, and during periods of heavy sweating or occlusive clothing. Cooling and skin care measures resolve most cases on their own, but the discomfort and recurrence in humid weather lead many people to look for supportive options. This list introduces remedies commonly discussed in homeopathic literature for prickly heat, purely as general information.
Important — Please Read

Please consult a qualified homeopath for individualised care and keep up cooling and skin hygiene measures alongside any remedy — do not self-medicate.
The 6 Remedies
Cantharis
Considered for prickly heat with intense burning and stinging, where the skin feels raw and irritated, sometimes with small blisters.
Apis Mellifica
One of the most frequently discussed remedies for hot, puffy, stinging skin eruptions that feel better with cool applications, matching the burning, prickling character of miliaria.
Urtica Urens
Traditionally used for itchy, blotchy eruptions resembling nettle-rash, worse from heat and touch, and commonly considered for heat-triggered skin reactions.
Sulphur
Suited to itching, burning skin that is worse from heat, bathing, and warmth of the bed, particularly in individuals prone to recurring skin flare-ups in summer.
Rhus Toxicodendron
Considered for intensely itchy eruptions that improve with continued gentle rubbing or movement, particularly when the rash follows sweating and heat exposure.
Belladonna
Traditionally used for hot, red, throbbing skin eruptions with a sudden onset, particularly in the acute, more inflamed presentations of heat rash.
