BBC Wildlife Magazine - - Wild October -

This small tree’s full ver­nac­u­lar name is ‘purg­ing buck­thorn’, so you would be well ad­vised to ex­clude its berries from your au­tum­nal for­ag­ing trips. Buck­thorn fruits, which ripen this month to re­sem­ble a diminu­tive black grape, are an in­tense lax­a­tive. They are best left to birds, which con­sume them re­gard­less of any ill ef­fects. Buck­thorn grows in hedgerows, scrub and woodland, and is the prin­ci­pal food­plant of brim­stone cater­pil­lars.
