Tribulus terrestris L. (TT) is an annual plant of the family Zygophyllaceae that has been used for generations to energize, vitalize, and improve sexual function and physical performance in men. The fruits and roots of TT have been used as a folk medicine for thousands of years in China, India, Sudan, and Pakistan. Numerous bioactive phytochemicals, such as saponins and flavonoids, have been isolated and identified from TT that are responsible alone or in combination for various pharmacological activities. This review provides a comprehensive overview of the traditional applications, phytochemistry, pharmacology and overuse of TT and provides evidence for better medicinal usage of TT.

In recent years, studies of traditional medicinal plants have gradually increased worldwide because the natural sources and variety of such plants allow them to complement modern pharmacological approaches. As computer technology has developed, in silico approaches such as virtual screening and network analysis have been widely utilized in efforts to elucidate the pharmacological basis of the functions of traditional medicinal plants. In the process of new drug discovery, the application of virtual screening and network pharmacology can enrich active compounds among the candidates and adequately indicate the mechanism of action of medicinal plants, reducing the cost and increasing the efficiency of the whole procedure. In this review, we first provide a detailed research routine for examining traditional medicinal plants by in silico techniques and elaborate on their theoretical principles. We also survey common databases, software programs and website tools that can be used for virtual screening and pharmacological network construction. Furthermore, we conclude with a simple example that illustrates the whole methodology, and we present perspectives on the development and application of this in silico methodology to reveal the pharmacological basis of the effects of traditional medicinal plants.

Impaired glucose tolerance (IGT) is a pre-diabetic state of hyperglycemia that is associated with insulin resistance, increased risk of type II diabetes, and cardiovascular pathology. Recently, investigators hypothesized that decreased vagus nerve activity may be the underlying mechanism of metabolic syndrome including obesity, elevated glucose levels, and high blood pressure.

Modern studies have shown that adaptogens can non-specifically enhance the resistance of human body under a wide range of external stress conditions with a multi-targeted and multi-channel network-like manner, especially by affect the immune-neuro-endocrine system and the hypothalamic–pituitary–adrenal axis. This review article draws the attention to the relationships of adaptogens, tonics from traditional Chinese medicine (TCM) and ginseng-like herbs worldwide, which all have similar plant sources and clinical applications. To clarify the sources and pharmacological mechanisms of these plant-originated adaptogens, which will provide useful information for the utilization of adaptogens to improve the human health. Meanwhile, the TCMs and the world-wide ginseng-like herbs from each region’s ethnopharmacology will be beneficial modernization and globalization.

Depressive disorders are the most common form of mental disorders in community and health care settings. Unfortunately, the treatment of Major Depressive Disorder (MDD) is far from satisfactory. Vagus nerve stimulation (VNS) is a relatively new and promising physical treatment for depressive disorders. One particularly appealing element of VNS is the long-term benefit in mood regulation. However, because this intervention involves surgery, perioperative risks, and potentially significant side effects, this treatment has been limited to those patients with treatment-resistant depression who have failed medication trials and exhausted established somatic treatments for major depression, due to intolerance or lack of response.

Acne vulgaris is a common inflammatory skin disease, affecting adolescents across the globe. Recent evidences underline that Propionibacterium acnes (P. acnes) promotes acne through Toll-like receptor (TLR) activation. Especially, Toll-like receptor 2 (TLR2) has emerged as one of the major classes of pattern recognition receptors (PRRs) that are recognizing P. acnes in the epidermis and responsible for inflammation. Although P. acnes has been known to be one of the major causes of acne vulgaris, an appropriate drug to alleviate acne pathogenesis is poorly developed. This review focuses on the molecular structure of TLR2 as well as mechanism how TLR2 recognize P. acnes to induce inflammatory cytokines, which is related to acne vulgaris pathogenesis. Rigorous study about P. acnes mediated by TLR2 activation may provide insight into novel therapeutic targets of acne vulgaris.
