Abstract

Abstract It is believed that herbal medicines act in a holistic way, but been derived from nature they can be specific in response. Herein, we review herbal medicines which are used for the treatment of cardiovascular diseases (CVDs) and their interactions with other drugs. CVDs have a high mortality rate and morbidity in the world, therefore, prevention and reduction of risk factors, which are associated with CVD, are the major tasks of healthcare professionals and scientists. Modern medicines despite having promising effects are unable to bring to a standstill the CVDs, consequently people are are paying attention to CAM (complementary and alternative medicines) -the herbal medicines.

Introduction

Herbal medicines can be defined as, plant structures capable of showing phytomedicinal or phytopharmaceutical effects. The peoples are looking outside the decorated glass of conventional medicines to improve their health care needs. In the light of critics and proponents the treatment of cardiovascular diseases with herbal medicines is a charged subject. However, medical practitioners can no longer turn a deaf ear to herbal medicines. The World Health Organization (WHO) estimated that approximately 17.1 million people died from CVDs and its complications in 2004, and the number of deaths will dramatically increase to almost 23.6 million by 2030 (WHO, 2010). Herbal medicine is a heritage that is thousands of years old and is still used by millions of people all over the world—even after the development of modern scientific medicine, however several fundamental questions are still unanswered. What are the mechanisms of action of the herbs? What are the precise targets of these herbs? What are the relationships between these herbals and diseases? How to explain one of the basic theories of TCM, i.e., “multiple herbal drugs can treat one disease”? Herbal medicine has been widely used in China as well as other Asian countries for the treatment of cardiovascular diseases for hundreds of years. Cardiovascular disease (CVD) is the major cause of mortality and morbidity in the Western world. Therefore, prevention and reduction of risk factors, which are associated with CVD, are the major tasks of health care professionals and scientists. According to the Centers for Disease Control and Prevention (CDC) and the American Heart Association, heart disease is the leading cause of death in the United States with a mortality rate of more than a quarter of total deaths in 2004. Angina (pain from decreased blood flow to the heart), coronary syndrome, heart failure, pulmonary embolism, arrhythmias, aortic valve disorders, or bacterial endocarditis are some of the cardiovascular diseases that account for the most deaths worldwide, with heart disease responsible for 7.2 million deaths in 2004.

Through the ages, humans have relied on nature for their basic needs for the production of foodstuffs, shelter, clothing, means of transportation, fertilizers, flavors and fragrances, and, not least, medicines. Apart from their cultural significance, herbal medicines are generally more accessible and affordable. There is evidence concerning the participation of reactive oxygen species (ROS) in the etiology and physiopathology of human diseases. Cardiovascular disease (CVD) is one of the top menaces of human lives and a global burning issue and CVD, encompasses a spectrum of diseases, including, Coronary artery disease,peripheral vascular disease,congestive heart failure, dyslipidemias, ,hypertension [1]. Despite being promising effects, peoples are turning faces away from modern medicines mainly due to unsatisfying treatment results, redundant side effects, Economic issues.During the last two to three decades, developed countries, such as the United States, Canada, Australia, and members of the European Union, judiciously promoted the use of herbal medicine in the form of complementary and alternative medicine. However, efficacy or safety of the majority of herbal medicines in CVDs has not been fully established through an evidence-based approach. Further, other issues, such as scientific, cultural, educational, economical, and legal, need to be addressed. Safety is a major concern for the use of herbs in humans. It is generally believed that herbal medicines approach a patient in a holistic way. Nevertheless, to make it easier to understand and to study these herbs, in this review, we chose to introduce these herbs one by one individually and even introduce the main components in molecular level. Following Table 1 depicts the role of herbal medicines in the treatment of CVDs [2].

Table 1: Herbal medicine their clinical use and pharmacological effects.

The theme of this MS is uncler.The materials including the effect of 34 kinds Japanese herbal medicines, anoxidant effect of resvertrol, effect of strawberry, etc, are loosely put together

Effectively put together. Effect of strawberry has been replaced by another exciting topic, that is troika of herbal medicines. Antioxidant effects of resveratrol are reorganized. Also effect of 34 kinds Japanese herbal medicines has been improved.

Effect of 34 kinds of japanese herbal medicines on sustainability of cardiac allograft survival

Herbal medicines have been used for over 3,000 years in Asia as alternative therapy for their varying effects and recently have become popular in Europe and the United States. In this study, X Jin et al investigated the effect of 34 kinds of traditional Japanese herbal medicines (prior to this gynecological effect also treated with herbal medicines [3], on alloimmune responses in a murine model of cardiac allograft transplantation [4-6]. In this study, the effect of 34 kinds of traditional Japanese herbal medicines of alloimmune responses in a murine model of cardiac allograft transplantation was examined at molecular level. Table 1 shows the major components found in all 34 Japanese herbal medicine.

Antioxidant effects of resveratrol in cardiovascular diseases.

Resveratrol—a natural polyphenolic compound—was first discovered in the 1940s. It has shown beneficial effects against most cardiovascular diseases. A large part of these effects are related to its antioxidant properties [7].

Structure of resveratrol:

Effects of resveratrol on antioxidant mechanisms protecting against oxidative cardiovascular pathophysiology: It has been recently demonstrated that resveratrol reduces endothelial dysfunction in vessel from dyslipidemic patients with hypertension; this antioxidant action of resveratrol was mediated by up regulation of manganese superoxide dismutase (Mn-SOD) via a mechanism dependent upon nuclear factor (erythroid-derived 2)-like 2 (NRF2). This finding in humans was in agreement with experimental models showing that resveratrol was able to increase Mn-SOD expression in the mouse myoblast line C2C12 via nuclear translocation and activation of sirtuin 1 (SIRT1), a NAD+-dependent class III histone deacetylase. It also hampers platelet aggregation and activation of phytoalexin seems to inhibit the interaction of platelets with collagen and thrombin in vitro in isolated platelets and in animal models. Reduction in the rate of cytochrome C oxidation by hydroxyl radicals Jiian et al. reported that resveratrol significantly reduced cytochrome C protein levels in the heart tissue of rats subjected to trauma-hemorrhage.Mechanism of action is shown in Figure 1.

Figure 1: Resveratrol reduces cardiovascular diseases.

Use of herbal medicines, evidence dominates over belief in case of treatment of cardiovascualar diseases.

Modern medicines used for the treatment of various cardiovascular diseases provide symptomatic relief or slow down the progress of disease. In the treatment of heart failure, adverse effects of medicines may be observed in the form of rise in frustration in patient, scientists have gone to apply extreme alternatives like gene therapy and stem cell therapy. Under such sensitive circumstances, understanding the high risk of morbidities and mortality of CVD hybrid with the limitations of modern medicines, there is an dire need to explore (Table 2) herbs for the prevention and possible, “cure” of CVDs.

Table 3: Clinical interaction between herbal medicines and conventional cardiovascular drugs [23].

The cardiovascular diseases that account for the most deaths worldwide, with heart disease responsible for 7.2 million deaths in 2004 [9] many of the components and complications of cardiovascular diseases including the damage caused by oxidants in the aftermath of ischemic heart failure. McCune investigated the role of these herbal medicines in cardiovascular. Flavonoids and other antioxidants have the ability to regulate the metabolism of cholesterol, triglyceride and induction of inflammatory cytokinese, which inhibit the build up of foam cells, platelets and fatty acids deposits in arteries.

The German Commission E Monographs, the standard reference for prescription herbal products in some of the countries of Europe, lists the following plants for treatment of cardiovascular indications: Ginkgo biloba leaf extract (Ginkgo biloba L.), onion (Allium cepa L.), motherwork herb (Leonuri cardiacae L.), hawthorn leaf with flower (Crataegus monogyna Jaquin emend. Lindmand or C. laevigata (Poiret) de Candolle), lily of the valley herb (Convallariae majalis L.), pheasants eye herb (Adonidis vernalis L.), squill (Urginea maritime (L.) Baker), butcher’s bloom (Ruscus aculeatus L.), camphor (Cinnamomum camphora (L.) Siebold), lavender flower (Lavandulae angustifolia Miller), rosemary leaf (Rosmarinus officinalis L.), scotch broom herb (Cytisus scoparius (L.) Link), garlic (Allium sativum L.), soy lecithin and phospholipid (Glycine max (L.) Merrill), Indian snakeroot (Rauwolfia serpentine (L.) Bentham ex Kurz), arnica flower (Arnica Montana L. or A. chamissonis Less. subsp. foliosa (Nutt.) Maguiere), sweet clover (Melilotus officinalis (L.) Pallas and/or M. altissimus Thuillier), and horse chestnut seed (Aesculus hippocastanum L).

Hawthorn

Hawthorn (Crataegus monogyna or laevigata frequently referred to as C. oxyacantha) has other common names such as may bush and white thorn and is found in Europe, North America, and Asia as a deciduous tree in the Rosaceae family [10]. Hawthorn contains polycyclic flavonoids including epicatechin, chlorogenic acid, rutin, isoquercitin, and hyperoside [11] .Vitexin-4-O-glucoside and vitexin- 2-O-rhamnoside have been described as the major flavonoids present in hawthorn leaves that are readily absorbed when the products are fed to rats [12]. Hawthorn shows antiarrhythmic properties. Many flavonoids found in it have shown increased coronary blood flow. Problems of heart contraction and blood flow can be successfully solved by using hawthorn.

Horse chestnut seed

Horse chestnut seed (Aesculus hippocastanum L.), of the family Hippocastanceae, is a medicinal tree species cultivated widely for ornamental and shade purposes.Horse chestnut is one of the top 20 herbal supplements sold in the United States with sales of $558946 in 2009 in the mass market alone [13]. Extracts of horse chestnut are commonly standardized to about 20% of triterpene saponin glycosides (the natural mix of these is commonly referred to as aescin). Aescin is found in A. hippocastanum seeds at the rate of 9.5% dry matter as well as the flavonoids quercetin, kaempherol, epicatechin, and anthocyanins; and the fatty acids lauric acid, palmitic acid, myristic acid, stearic acid, arachidic acid, and oleic acid. Dosages in these trials ranged from 100 to 150 mg aescin daily.Experiments in animal and cell culture systems have demonstrated the effectiveness of horse chestnut in decreasing inflammation and platelet aggregation, increasing venous contractions and protecting venous endothelium relaxation.In ADP-induced human platelet aggregation studies, it was determined that horse chestnut extract reduced platelet aggregation. Endothelial dysfunction is a precursor to hypertension, atherosclerotic disease, hypercholesterolemia,and chronic venous insufficiency (CVI). There are many studies on the effects of horse chestnut extracts on the traits and symptoms of CVI (these can includevaricose veins, venous ulcers, leg-tiredness, swelling, and the hardening of the skin caused by lipidermatosclerosis) [14,15]

Ginkgo

Ginkgo (Ginkgo biloba L.) is an ancient tree species that has been used as a heart medicine in Chinese phytomedicine since at least 1509 .The German Commission E Monographs listed the leaf extract as an approved herb due to established results in experimental research. In the United States, it is one of the top-selling herbal supplements with over 16 million US$ in sales in the mass market in 2009 and $4 276 489 in the US natural and heath food retailers alone. Ginkgo leaves have diterpene terpenoids (chiefly the ginkgolides and bilobalide) and flavonoids (including quercetin, kaempferol, and isorhamnetin). Suggested dosages are between 120 and 240 mg daily in multiple increments.

Its free radical scavenging action has been responsible for protecting nitric oxide and prostaglandin I2 activity, thereby ensuring continued blood flow via smooth muscle relaxation .clinical trials have reported antioxidant activity, improved blood flow, and anti-inflammatory properties against cardiovascular disease development.

Cardiovascular herbal medicines: The risk of drug interaction

Herbal medicines are widely used for the treatment of cardiovascular diseases, so it is important to support credible research on the use of herbal medicines by focusing and explaining herb-drug interactions to provide a reliable alternative path to cardiovascular patients [16]. Recent data have revealed that all herbal medicines contain many active ingredients including those used in the therapy of cardiovascular diseases [17-21], Like all the other things of the world (excess of everything is very bad) herbal medicines (HB) are not always right, so medical professionals must care and know that HBs are not completely risk free [22].

Table 3 clinical interaction between herbal medicines and conventional cardiovascular drugs [23].

PC-PCS is a mixture of eight herbal drugs, namely, Dendrathema morofolium (Chrysanthemum), Isatis indigotica (Dyer’s woad), and Glycyrrhiza glabra (liquorice), Ganoderma lucidum (reishi), Panax pseudoginseng (san-qui ginseng), Rabdosia rubescens (rubescens), Serenoa repens (saw palmetto) and Scutellaria bacicalensis (Baikal skullcap).

Conclusion

Herbal medicine, almost by definition, is the application of a group of compounds rather than single pure entities. These compounds can have synergistic or antagonistic properties that affect how the compounds interact and the potential to affect multiple aspects of a disease. Plant products, whether food, herb, or spice, can contribute antioxidants to ameliorate symptoms of cardiovascular diseases. Hawthorn can improve exercise tolerance, pressure-heart rate product, fatigue, maximal workload, and has antiarrhythmic properties. Gingko’s antioxidant and anti-inflammatory properties improve brachial artery endothelial vasomotor function (flow-mediated dilation) and coronary artery blood flow.Horse chestnut seed decreases inflammation and platelet aggregation, increases venous contractions, and protects venous endothelium relaxation in animal and cell studies, while in humans it has been shown to improve conditions of CVI. The search for plant medicines should encompass the food, herb, and spice use of cultures around the world. Human pharmacokinetic studies are needed on plants used for food, herbs, and spice
