Hawthorn (Greek Crataegus) is a beautiful plant that grows in all continents now. The leaves, flowers and berries have health benefits and they are used to produce medicine for heart diseases.

The British Homeopathic Review revealed of Dr. Green (Ireland):
“… For many years had a reputation for the cure of heart disease that caused patients to flock to him from all parts of the United Kingdom. He cured the most of them and amassed considerable wealth by means of his secret. 

For, contrary to the code, he, though a physician in good standing, refused to reveal the remedy to his professional brethren. After his death … (in 1894), his daughter, a Mrs. Graham, revealed the name of the remedy her father had used so successfully. It is Crataegus oxycanthus …”

The health qualities of Hawthorn are still being researched:
‘This study was to investigate the anticancer effects of the peel polyphenolic extract (HPP) and flesh polyphenolic extract (HFP) from hawthorn fruit in human MCF-7 breast cancer cells. It was found that the polyphenol and flavonoid contents of HPP were significant higher than that of HFP. Both HPP and HFP inhibited cell growth in a dose-dependent manner with …, suggesting that HPP was more effective against MCF-7 cells than HFP. … All these findings indicate that hawthorn fruit, especially its peel, is an excellent source of natural chemopreventive agents in the treatment of breast cancer.” (Food Chemistry, Volume 141, Issue 2, 15 November 2013, Pages 1008-1018)
