The medicinal properties of hawthorn (Crataegus spp., a genus comprising approximately 300 species) have been utilized by many cultures for a variety of therapeutic purposes for many centuries. In the Western world cardiovascular disease (CVD) has become one of the single most significant causes of premature death. Echoing this situation, more recent research into the therapeutic benefits of ha...

In this investigation, two species of Crataegus (hawthorn) were chosen because their polyphenolic constituents have recently received greater attention for the treatment of patients with severe heart disease. One-year-old plants of hawthorn (Crataegus laevigata and C. monogyna) were subjected to water-deficit (continuous water deprivation), cold (4 degrees C), flooding (immersion of roots of pl...

Whether phytophagous insects can speciate in sympatry when they shift and adapt to new host plants is a controversial question. One essential requirement for sympatric speciation is that disruptive selection outweighs gene flow between insect populations using different host plants. Empirical support for host-related selection (i.e., fitness trade-offs) is scant, however. Here, we test for host...

Combinations of medicinal plants ensure the collective work several active components, which can lead to an additive or synergistic effect. We have chosen bur-marigold-calendula-hawthorn combination obtain antiallergic herbal medicine, in bur-marigold is main plant, calendula a helper plant that helps fight against accompanying symptoms, and hawthorn harmonizes action first 2 plants.

A review with 54 references covers all aspects of hawthorn, the genus Crataegus, including its traditional uses, chemical constituents, pharmacological activities, and clinical effects. Although the effectiveness of hawthorn on the treatment of cardiovascular diseases has received extensive attention worldwide, further scientific research on various areas such as pharmacokinetics, mechanism of ...

This paper evaluated the antibacterial effect of medlar and hawthorn compound extract in vitro. Water extract method and ethanol extraction method was adopted to prepare the compound extracts, and disc diffusion method and improved test tube doubling dilution method were used to conduct the antibacterial test on the two common pathogenic bacteria, Staphylococcus aureus and Klebsiella pneumonia,...

Hawthorn (Crataegus spp. L.) is a native fruit of great economic importance in Turkey and has been widely using in folk medicine particularly for the treatment of mild heart diseases for a long time. In the study, 18 previously selected hawthorn genotypes belong to several Crataegus species grown in the hawthorn repository collection in Malatya province in Turkey were evaluated. Fruit mass and ...

BACKGROUND Hawthorn (Crataegus laevigata) leaves, flowers and berries are used by herbal practitioners in the UK to treat hypertension in conjunction with prescribed drugs. Small-scale human studies support this approach. AIM To investigate the effects of hawthorn for hypertension in patients with type 2 diabetes taking prescribed drugs. DESIGN OF STUDY Randomised controlled trial. SETTIN...

Ecological speciation with gene flow may be an important mode of diversification for phytophagous insects. The recent shift of Rhagoletis pomonella from its native host downy hawthorn (Crataegus mollis) to introduced apple (Malus domestica) in the northeastern United States is a classic example of sympatric host race formation. Here, we test whether R. pomonella has similarly formed host races ...
