Hawthorn
Crataegus spp.
A familiar, smaller tree common throughout the UK and often found on lonely moors, mountains and inhospitable places. Hawthorn is for the for the heart and the arteries. It has an interestingly amphoteric (balancing) effect of the blood pressure; being useful in both high and low blood pressures. It strengthens the hearts beat but without increasing its rate.
It is a safe remedy and can be taken daily over time - but seek skilled advice from a herbalist
Both the flowering tops and the berries are used, so harvest time is both spring and autumn.
