Camphor, which comes from the Cinnamomum camphora tree, is used in skin products to treat rheumatism, low blood pressure, bronchitis, cough and nervous heart complaints, according to the University of Texas at El Paso, or UTEP. For respiratory problems, some people apply camphor-containing products onto the chest and throat. In other products, camphor essential oil is blended with other oils, such as almond oil, and used to alleviate itching, raise blood pressure, or improve capillary circulation. Do not use camphor on children younger than two. Using products with camphor can have side effects, some potentially severe, so consult a doctor before applying them.
Skin Reaction
You may experience irritation or develop contact eczema when you apply camphor to your skin, according to UTEP. These can include dryness and itching, reports Drugs.com. If you suffer from contact dermatitis, avoid scratching the area, advises the Mayo Clinic. You may apply cool wet compresses and should wear cotton clothing that has a smooth texture. Speak to your doctor before applying medicines or creams.
Allergic Reactions
Some folks have allergic reactions to camphor. If you experience hives, a rash, difficulty breathing, tightness in your chest, severe irritation where you applied the camphor, or your mouth, lips, tongue or face swell, seek immediate medical attention.
Seizures
If you have epilepsy or Parkinson's disease, do not use camphor because it can cause a seizure, advises UTEP. Parkinson's disease is a progressive nervous system disorder that affects movement. Epilepsy is a condition in which electrical signals generated by the brain cause recurring seizures, according to the Mayo Clinic.
Convulsions and Respiratory Arrest
If you are using camphor for a respiratory ailment, don't apply camphor near or directly to nostrils, especially in small children or an asthmatic person, advises UTEP. It can cause bronchial spasms and convulsions, which can lead to respiratory arrest. Also, use options that are less toxic than camphor to treat upper respiratory tract infections.
Intoxication
You should not use camphor for long periods of time, according to James A. Duke's "Handbook of Medicinal Herbs." Camphor applied to skin for prolonged periods of time may end up stored in your body fat. This can cause intoxication, according to UTEP, and symptoms can include delirium and confusion.
Miscellaneous Warnings
You should not apply camphor oil to burned, broken or injured skin, according to "The Green Pharmacy Herbal Handbook", also written by Duke. And it's unsafe to use camphor if you are pregnant or nursing because it is readily absorbed by your skin and able to cross the placenta, according to the International Programme on Chemical Safety. It has been used to induce abortions.
