We report a case of severe unilateral epistaxis requiring surgical arrest of bleeding, via endoscopic sphenopalatine artery ligation and anterior ethmoidal artery ligation. This followed recreational nasal insertion of St John's wort (Hypericum perforatum). Interactions between this substance and prescribed drugs have been described following oral ingestion. However, this unusual case highlights a further, worrying potential rhinological side effect of this substance.

Hypericum Perforatum L

The effect of type of herbicide and time and rate of application on the reduction in ground cover of St John's wort (Hypericum perforatum L.) was determined at Orange, New South Wales. In January, April, July and November 1988, 8 herbicide treatments including the currently used glyphosate and picloram + 2,4-D were applied to vigorously growing H. perforaturn, and the reduction in percentage ground cover was recorded in December 1989. Ineffective herbicides (a.i./ha) were tebuthiuron, 0.8-6.4 kg; metsulfuron, 5-20 g; and paraquat + diquat, 0.4 + 0.5 kg. The addition of metsulfuron (2.5 g a.i./ha) to glyphosate (0.9 and 1.8 kg a.i./ha) did not increase the effectiveness of the latter. Effective herbicides (kg a.i./ha) were triclopyr + picloram, 0.6 + 0.2; picloram + 2,4-D, 0.2 + 0.8; glyphosate, 1.8; and triclopyr, 1.92. There was a strong trend for these herbicides to be more effective in January and November than in April and July. Based on price, effectiveness and selectivity, triclopyr + picloram would be preferred to the other herbicides for boom and spot spraying, and glyphosate would be the only herbicide suitable for aerial application prior to sowing improved pastures on non-arable land.

Anterior ethmoidal artery ligation is a well-established surgical procedure in the management of epistaxis. We describe a procedure of anterior ethmoidal artery ligation via minimal access external surgery with the use of a rigid endoscope. This is, as far as we are aware, the first description of an external approach endoscopic anterior ethmoidal artery ligation.
