In: Arzneimittelforschung (1995 Nov) 45(11):1157-61 ISSN: 0004-4172 The hawthorn extract LI 132 (crataegus), prepared from leaves and flowers, and standardised to 2.2% flavonoids, was investigated with respect to its effect on (1) the contraction, (2) the energy-turnover and (3) the apparent refractory period (t(ref)) of isolated cardiac myocytes from adult rats.
Crataegus extract (0.01 or 0.05%) was applied to the heart from 5 min before ischemia through the first 10 min after reperfusion.
In the heart treated with the high concentration of Crataegus extract, the reperfusion-induced recovery of the energy metabolism was accelerated, and the level of lactate during ischemia was lower than that in the control heart, although the myocardial levels of free fatty acids during ischemia and reperfusion were not greatly affected.

Crataegus, commonly called hawthorn, is a well-known herb in traditional Chinese medicine and is an herb remedy in cultures throughout much of the world where there is a temperate climate supporting growth of the trees, especially in Europe.

Some years ago it struck me that crataegus (hawthorn), a nutritive heart tonic used in a wide variety of cardiovascular disorders, might be well-indicated for certain emotional states that lead us to “close down our hearts,” and that prescribing Crataegus at these times might, in fact, help to prevent cardiovascular disease in later life.
Crataegus, in my experience, has an ability to open out hearts again when disappointments or grief led us to close down or distrust.
It struck me that since crataegus is useful for heart conditions that involve a sense of constriction and closing down, it might also be useful for lung conditions with the same symptoms of constriction and tightness in the chest.
