Camphor Induced Myocarditis: A Case Report

Abstract

Availability of camphor containing products in households is not uncommon. In certain parts of the world, camphor is used in medicines intended for enteral intake and also used as a flavoring agent in edibles. Toxicity due to ingestion of camphor has been described and in severe forms it manifests as seizures, apnea, asystole, circulatory collapse and death. We report myocarditis associated with ingestion of a large dose of camphor. The electrocardiogram revealed prolonged QRS duration and QTc interval. 2D- Echo images revealed features of acute myocarditis. The changes were transient and resolved in a short time while the patient was on supportive therapy. The medicinal uses of camphor are unsupported by evidence and safer, more effective alternatives exist. Its use in household products and edibles should be discouraged.

Anticholinergic Syndrome and Supraventricular Tachycardia Caused by Lavender Tea Toxicity

“…QT and prolonged QTc in electrocardiograms and acute myocarditis due to camphor toxicity have been reported in one case in the literature. 10 Since our center was not able to measure camphor levels, we could not determine the plasma level in our patient.…”

“…Other adverse effects are tachycardia, elevated liver enzymes, and central nervous system and cardiovascular system toxicity. 9,10 The toxic effect on the central nervous system can result in mental confusion and convulsion. Severe poisoning can cause status epilepticus, apnea, asystole, circulatory collapse and death.…”

“…Severe poisoning can cause status epilepticus, apnea, asystole, circulatory collapse and death. 10 Serious central nervous system toxicity related to accidental camphor exposure, especially in children, has been reported in the literature. Camphor exhibits cardiovascular toxicity and it is known to cause hypertension and tachycardia during the early stage of toxicity and to cause peripheral vascular collapse and shock in serious cases.…”

Environmental Toxins and the Heart

“…Ingestion of 2 g of camphor is sufficient to produce toxic effects in adults. 328 Initial symptoms may occur within 5 to 15 min after ingestion and include nausea and vomiting, oral and epigastric burning, a feeling of warmth, and a headache. These symptoms may progress to altered mental status, convulsions, coma, and death.…”

An Elementary Framework for Judging the Cardiovascular Toxicity of Carbon Soot: Experiences from an Occupational Health Survey of Diamond Industry Workers

“…Toxic effects of chemicals and elements on cardiovascular system are being reported in literature more frequently [11,12]. Possible linkage of airborne particulate matter and adverse cardio-respiratory endpoints has been a frequent topic for epidemiological investigation [1].…”
