Tree lore and folkloreAlder wood is a lure for woodworm, (as the beetles lay their eggs in alder in preference to other wood), so branches were cut and put in cupboards to prevent woodworm. There are few references to alder being used in medicine, for instance, in the 19th Century it was used as a substitute for quinine in easing fevers. In Norfolk, the bark was used for treating burns, piles and ‘heart trouble’. Alder is common in Ireland and tradition has it that it was unlucky to pass an alder on a journey, possibly due to the tree growing in marshy terrain!
