HAWTHORN, MAY, WHITETHORN
Given by herbalists, both East
and West, the flowers, leaves and fruit form one of the most useful heart
remedies, and improve the heart's action and circulation.
Hawthorn flowers are reputed to have magical properties, such as causing a death in the family if they are taken into the
home, which is why superstitious people will not have them inside. The plant is also said to have been the source of Christ's crown of thorns.
It is one of the most useful herbal heart remedies. Native to Europe, north Africa and western Asia, this shrub or small tree grows to 10 m (30 ft) and has deeply lobed,
dark-green leaves. Clusters of white flowers appear from early to midsummer, followed by oval red berries in the autumn.
