Ecbalium elaterium (squirting cucumber)--remedy or poison?

Ecbalium elaterium is a plant endemic to the Mediterranean basin. Its roots and cucumber-shaped fruit have been used in folk medicine since antiquity. The alleged uses of the fruit juice are as a potent cathartic, analgesic, and antiinflammatory agent. Cucurbitacin B, a triterpene derivative is the active antiinflammatory principal.

We present a series of 13 patients who were exposed to the juice of Ecbalium elaterium in its natural form. In 3 patients, exposure was intranasal for the treatment of sinusitis or liver cirrhosis. In 3 other cases, children ingested the fruit unwittingly. In 6 patients, exposure was ocular and, in one, dermal. Within minutes of exposure, the patients exhibited irritation of mucous membranes at various degrees of severity manifested as edema of pharynx, dyspnea, drooling, dysphagia, vomiting, conjunctivitis, corneal edema, and erosion, depending on the route of the exposure. Recovery began within several to 24 hours after administration of oxygen, steroids, antihistamines, and beta-2-agonists. Ocular exposures responded to topical steroid and antibiotic eyedrops within a few days. The toddler with the dermal exposure remained asymptomatic.

Exposure to the juice of Ecbalium elaterium, mainly in its undiluted form, may cause irritation of mucous membranes, supposedly of inflammatory nature. Patients exposed orally or intranasally should be closely followed for upper airway obstruction. Patients exposed ocularly should have their eyes promptly irrigated to prevent corneal and conjunctival injury.
