There are two bryonies, named white and black after the colour of their roots, both looking very similar for most of the year since they each have mid-green ivy-like leaves, small insignificant greenish white male and female flowers followed by red berries, and they climb up hawthorn with abandon. However they are completely unrelated to each other. White bryony, Bryonia dioica, is a member of the curcurbitae family (ie courgettes and melons) so climbs with tendrils, and is dioecious, while Black Bryony, Tamus communis, belongs to the Dioscoreaceae family (ie yams), climbs by twining, and is monoecious. Both are poisonous in all parts.Black bryony berries and juice or pulp from the root have been applied directly to the skin for bruises, strains, gout, rheumatism and hair loss because the calcium oxalate it contains as crystals irritate (or stimulate?) the skin. It has also been used to cause vomiting in careful doses, and when mixed with wine or honey, black bryony has been used for gravel or asthma. An overdose is likely to cause a painful death however. All parts also contain saponins, another poison, although one which is normally deactivated by cooking – but the young shoots are cooked and eaten like asparagus in southern France, Spain, Portugal, Italy, Croatia and Greece.
I managed to meet Black Bryony in meditation, and found a very interesting energy which was willing to communicate with me, appearing briefly in a dark female form and very beautiful. Its element is fire, and its focus is transformation – hence is medical uses. But transformation can be destructive to some if they are not willing to change, to let some parts die down. It was used in alchemy for this purpose. [I cannot find any evidence for this as yet, although I’m not an alchemist so it may turn up…] It has been particularly active along the lane to create the transformation that I have seen this year. It has developed strong roots in the course of this work so will continue to grow well there, but doesn’t need to spread further. It also brings harmony, creating links between species. It does not help the fiery aspects of will, or of strong focus and intention.
