To increase your overall strength, at the New Moon in spring cut off a young oak twig, being sure to ask permission of the dryad beforehand. If refused, oak bark is available from many herbalists and is a respectable substitute. Strip the twig of its shiny bark, and place this or the store-bought dried bark in a saucepan of water. Boil until thoroughly infused. As you work, consider oaken qualities: fertility, sturdiness, durability, deep-rooted-ness. Know that in this brew, these properties are concentrated. If you are in full health and not pregnant, for optimum effect, take the potion as tea. If frail or if preferred, add to your bath. In both cases the important factor is to feel the properties of oak entering and fortifying your system. Entreat the spirit of the sacred tree to protect you. Using a ribbon and the leftover leaves, create a bouquet of thanks to this most ancient of benefactors.
