Preparation methods
- Steam Distillation: Camphor is derived from the wood and leaves of the tree through steam distillation. The wood is steam-distilled to yield essential oil.
- Decoction: Powdered wood can be boiled to make a decoction.
- Oil Infusion: Camphor can be dissolved in warm sesame oil for chest application or mixed with coconut oil for muscle pain.
- Tablets: Camphor is also available in tablet form for external or inhalation use, but avoid internal consumption without guidance.
Contraindications
- Internal use: Use cautiously and under guidance, as it is a potent herb.
- Exercise caution when prescribing herbs for patients taking drugs with a narrow therapeutic window.
- Avoid excessive doses of laxative herbs or potassium-depleting diuretics.
- Contraindicated with Kapotamamsa Herb-Animal origin drug interaction.
- Monitor patients frequently if they have impaired heart, liver, or kidney function.
- Exercise caution in elderly patients and pregnant women.
- Stop all herbs approximately one week before surgery.
Side effects
- Camphor is toxic if ingested in large amounts and should only be used externally or for inhalation.
- Excessive use can cause dizziness, nausea, or headaches.
- Topical use may cause redness, itching, or rashes. Dilute camphor in a carrier oil before application.
- Overuse in steam inhalation can trigger bronchospasm in asthma patients. High concentrations of camphor fumes can irritate the respiratory tract, causing coughing, wheezing, and shortness of breath.
- Ingesting even small amounts of camphor can lead to severe health issues, including nausea, vomiting, abdominal pain, seizures, and central nervous system depression.
- Camphor is not suitable for pregnant or nursing mothers.
- Camphor is possibly unsafe in children when applied to the skin, and is unsafe when taken by mouth. Seizures and death can occur.
Interactions
- Karpoor may interact with sedatives, blood thinners, and other medications.
- May potentiate anticonvulsants.
- Avoid with warfarin due to potential CYP450 interactions.
- It is best to avoid its usage in epilepsy and Parkinson's disease patients.
Clinical evidence
Limited clinical trials suggest potential benefits of Ghanasara (Camphor) in respiratory conditions and osteoarthritis. A clinical trial reported significant ease in breathing and reduced phlegm viscosity in bronchitis patients inhaling camphor steam for 5 days. A randomized study showed that a 5% camphor gel, applied twice daily, relieved osteoarthritis knee pain by up to 30% over a placebo after 4 weeks. Clinical trials for this therapeutic plant have not yet been carried out.
