Indications
Camphor is used on the skin in balms, rubs, creams and gels, often together with Menthol, Methyl Salicylate or Eucalyptus oil. It gives short-term relief of muscle aches, back pain, sprains, joint pain and minor itching. Chest rubs containing camphor are used to ease the feeling of a blocked nose and cough from a cold.
How It Works
Camphor creates a cooling then warming feeling on the skin. This mild irritation distracts from the pain underneath (counter-irritant effect). Its strong vapour gives a feeling of easier breathing, though it does not cure a cold.
Dosage and Administration
Adults and children over 2 years: apply a thin layer to the painful area and rub in gently, up to 3 or 4 times a day. Chest rubs: rub on the chest and throat, up to 3 times a day. Wash hands after use. For skin use only: never swallow it, and never put it in the nose, mouth, eyes or on the face of a young child.
Interactions
No important interactions with medicines are known when used on the skin. Do not use it with a heating pad, hot water bottle or tight bandage over the same area, as this can cause burns.
Contraindications
- Children under 2 years.
- Broken, burnt or irritated skin, and wounds.
- Allergy to camphor or any ingredient.
Side Effects
Mild redness, stinging or a burning feeling on the skin; rarely a rash. Get urgent medical help if anyone, especially a child, swallows a camphor product, even a small amount, or if there is difficulty breathing, fits (seizures) or severe skin burning.
Pregnancy and Lactation
Small amounts on unbroken skin for a short time are generally considered acceptable, but ask a doctor before regular use. Never swallow it. When breastfeeding, do not apply it to the breast or chest where the baby may touch or breathe it closely.
Precautions and Warnings
Swallowing camphor is dangerous and can cause fits within minutes, especially in children. Keep products well away from children. Do not heat camphor products in a microwave or add them to hot water for steam, as this can cause burns. Stop using it and see a doctor if pain lasts more than 7 days or keeps coming back.
Overdose
If swallowed: burning in the mouth, vomiting, confusion, fits and loss of consciousness can happen quickly. Go to a hospital straight away; do not make the person vomit.
Therapeutic Class
Topical counter-irritant (rubefacient).
Storage
Store below 30°C with the lid tightly closed, away from heat and open flame (camphor burns easily) and out of the reach of children.
