Yewberry

Indeed the form, as well as the foliage of the shrub — it is not worthy of being called a tree — is very like that of a Yew. The fruit, when ripe, is the same colour and size, and has about as much taste as a Yewberry.

Amongst the herbs to be administered when the charm was sung over him were a yew-berry, lupin, helenium, marsh mallow, dock elder, wormwood and strawberry leaves.
