Cardio/cerebral-vascular diseases seriously threaten human health and are the leading cause of death. As such, there is great interest in identifying a potential mechanism that controls the development process of cardio/cerebral vascular diseases. Present studies demonstrate that inflammasomes play an important role in the process of ischemic cardio/cerebral vascular diseases (ICCVDs). Among the pathological process of ICCVDs, inflammasomes activated the sterile inflammatory response that accelerated the development of diseases and aggravated the acute lesion of tissue. As the most thoroughly studied inflammasome, the NLRP3 inflammasome has been proven to be a potential therapeutic target for ICCVDs. In this review, we summarized the mechanisms of Chinese herbal medicine which can affect ICCVDs via the regulation of the NLRP3 inflammasome. Our study discovers that active compounds of Chinese medicines have a negative effect on NLRP3 in different ICCVDs models. Astragaloside IV may influence the receptor of the cell membrane to inhibit NLRP3 activation. Resveratrol, colchicinesis, salvianolic acid B, chrysophanol and sulforaphane may directly damage the formation of NLRP3 by inhibiting ASC or Caspase-1. Most of the active natural compounds can negatively regulate the downstream products of NLRP3 inflammasome such as IL-18 and IL1$\beta$. In addition, Chinese medicines such as sinomenine, ruscogenin, resveratrol, arctigenin and cepharanthineas may downregulate NLRP3 inflammasome by inducing autophagy activation. Due to the advantages of multi-target effects, Chinese herbal medicine can be treated as a splendid therapy for ICCVDs by inhibiting NLRP3 inflammasome.

Neuraminidase, also known as sialidase, is ubiquitous in animals and microorganisms. It is predominantly distributed in the cell membrane, cytoplasmic vesicles, and lysosomes. Neuraminidase generally recognizes the sialic acid glycosidic bonds at the ends of glycoproteins or glycolipids and enzymatically removes sialic acid. There are four types of neuraminidases, named as Neu1, Neu2, Neu3, and Neu4. Among them, Neu1 is the most abundant in mammals. Recent studies have revealed the involvement of Neu1 in several diseases, including cardiovascular diseases, diabetes, cancers, and neurological disorders. In this review, we center the attention to the role of Neu1 in cardiovascular diseases, including atherosclerosis, ischemic myocardial injury, cerebrovascular disease, congenital heart disease, and pulmonary embolism. We also summarize inhibitors from Chinese herbal medicines (CHMs) in inhibiting virus neuraminidase or human Neu1. Many Chinese herbs and Chinese herb preparations, such as Lonicerae Japonicae Flos, Scutellariae Radix, Yupingfeng San, and Huanglian Jiedu Decoction, have neuraminidase inhibitory activity. We hope to highlight the emerging role of Neu1 in humans and potentially titillate interest for further studies in this area.

The treatment of cardiovascular diseases and obesity, two diseases posing a major risk to human health, has been plagued by the scarcity of potent and effective medication with fewer side effects. To address this problem, numerous efforts, and some progress, have been made. Among possible treatments are some medicinal herbs; particularly promising is Alisma orientale (AO). In the last decade, an increasing amount of research has shown that AO has some desirable therapeutic effects on cardiovascular diseases and obesity. Because of its efficacy, natural origin, and minimal adverse effects, AO has aroused great attention. Based on this, this review provides an overview of the latest progress from the last decade regarding the pharmacological and therapeutic effects, molecular mechanisms, and related effective constituents of AO in the treatment of cardiovascular diseases and obesity. Results from the research currently available reveal that active constituents of AO, such as alisol B 23-acetate, alisol A 24-acetace, and alisol A, have been proven to be effective for treating cardiovascular diseases by modulating the lipid metabolism of macrophages, improving the biological behavior of vascular smooth muscle cells (VSMCs), and enhancing anti-inflammatory effects. Moreover, the active constituents of AO can also intervene in obesity by modulating abnormal glucose and lipid metabolism and fat decomposition of the body by activating the AMPK- and PPAR-related signaling pathways. In summation, based upon our research of available literature, this review reveals that AO and its active constituents have a great potential to be used as drugs for treating cardiovascular diseases and ameliorating obesity.

Phytochemical flavonoids have been proven to be effective in treating various disorders, including cardiovascular diseases. Acacetin is a natural flavone with diverse pharmacological effects, uniquely including atrial-selective anti-atrial fibrillation (AF) via the inhibition of the atrial specific potassium channel currents $I_{\mathrm{\text{Kur}}}$ (ultra-rapidly delayed rectifier potassium current), $I_{\mathrm{\text{KACh}}}$ (acetylcholine-activated potassium current), $I_{\mathrm{\text{sKCa}}}$ (calcium-activated small conductance potassium current), and $I_{\mathrm{\text{to}}}$ (transient outward potassium current). $I_{\mathrm{\text{to}}}$ inhibition by acacetin, notably, suppresses experimental J-wave syndromes. In addition, acacetin provides extensive cardiovascular protection against ischemia/reperfusion injury, cardiomyopathies/heart failure, autoimmune myocarditis, pulmonary artery hypertension, vascular remodeling, and atherosclerosis by restoring the downregulated intracellular signaling pathway of Sirt1/AMPK/PGC-1α followed by increasing Nrf2/HO-1/SOD thereby inhibiting oxidation, inflammation, and apoptosis. This review provides an integrated insight into the capabilities of acacetin as a drug candidate for treating cardiovascular diseases, especially atrial fibrillation and cardiomyopathies/heart failure.

Panax notoginseng (PN) root is a renowned nutritional supplement, health food additive, and traditional medicine that maintains homeostasis within the human microcirculatory system. Notoginsenoside R1 (NG-R1), an active compound derived from PN root, has been reported to possess various pharmacological activities, including anti-inflammatory, antioxidant, anticancer, antimicrobial, and angiogenic effects. However, NG-R1’s pharmacokinetic properties and pharmacological activities have not been systematically elucidated. In this paper, the pharmacokinetic properties of NG-R1, its pharmacological effects, mechanisms of actions, and structure-activity relationship have been reviewed. Notably, NG-R1 inhibits tumor necrosis factor α (TNF-α) expression, enhances the expression of nuclear factor erythroid 2-related factor 2 (NRF2), and enhances the expression of vascular endothelial growth factor receptor (VEGFR). The pharmacological effects of NG-R1 are associated with the modulation of several signaling pathways, such as mitogen-activated protein kinase (MAPK)/nuclear factor κ-B (NF-κB), NRF2/antioxidant response element (ARE), Wnt/β-catenin, and phosphoinositide-3 kinase (PI3K)/protein kinase B (AKT). NG-R1 offers potentially protective effects against numerous diseases, including cardiovascular, neurological, renal, pulmonary, bone, and diabetes-related conditions. Although the pharmacological activities and diverse effects of NG-R1 have been demonstrated in various diseases, its clinical applications are limited by poor bioavailability. Several strategies have been explored to improve the pharmacokinetic profile of NG-R1, making it a promising candidate for drug development.

Despite the great achievements of the evidence-based modern medicine and pharmacology, traditional Greco-Arab and Islamic Medicine-based herbal remedies are currently becoming more popular in Arab and Islamic world. Historical circumstances and the belief that these remedies are prepared according to the principles of Greco-Arab and Islamic Medicine, which was developed during the Golden Age of Arab-Islamic civilization. This medical system has influenced the fates and fortunes of countless human beings all over the world and it formed the roots from which modern Western Medicine and pharmacology arose. There is no doubt that the earlier Greco-Roman scholarly medical literature was the stem from which much Arab-Islamic Medicine grew, just as, several centuries later, Arab-Islamic Medicine was the core of late middle ages and early European medical system.

To compete with the growing pharmaceutical market, there is an urgency to utilize scientifically validated herbal products. Therefore, policy-makers in the Arab and Islamic world are forced to establish standardization and regulatory measures that regulate the quality, availability, and preservation of these products. Public demand has also grown for evidence on the safety and efficacy of herbal products as well as for national regulations for traditional healers and caregivers. This chapter provides a comprehensive overview on Traditional Arab-Islamic Herbal Medicine including the historical background, medical innovations introduced by Arab physicians, methods of therapies, and a state of the art and prospect description of Traditional Arab Herbal Medicine.
