Xanthii fructus (XF) has long been used to treat a variety of inflammatory conditions in Korean traditional medicine, but the underlying mechanisms that could explain the anti-inflammatory actions of XF remain largely unknown. ⋯ Taken together, our findings support that XF inhibits LPS-induced inflammatory responses by blocking NF-κB activation, inhibiting JNK/p38 MAPK phosphorylation, and enhancing HO-1 expression in macrophages, suggesting that it could be an attractive therapeutic candidate for various inflammatory diseases.

The modified-Chungsimyeolda-tang (DG) is an important traditional Korean herbal formula used in traditional oriental medicine for treatment of cerebrovascular disorders, including stroke. The formula is based on the book "Dongui Sasang Shinpyun". ⋯ The treatment with DG resulted in prophylactic effects on MPTP-induced Parkinsonian bradykinesia and the immunohistochemical analysis showed that DG provided the neuroprotection against the MPP(+)-induced dopaminergic neurons loss through the anti-apoptosis effect. The present results suggested that it might be possible to use DG for the prevention of substantia nigra pars compacta (SNpc) degeneration induced by exposure to the toxic substances, such as MPTP/MPP(+), in PD mouse model.

Plants of the genus Mahonia Nuttall (Berberidaceae) have a long history of medical use in Traditional Chinese Medicine (TCM) for the treatment of a wide range of health disorders, such as tuberculosis, periodontitis, dysentery, pharyngolaryngitis, eczema, and wounds. In the theory of TCM, most Mahonia species exert the effects of relieving internal heat, eliminating dampness, removing toxins, suppressing pain, promoting blood circulation, inhibiting cough and alleviating inflammation. The aim of the review is to provide comprehensive summary on ethnopharmacology, phytochemistry, pharmacology, toxicology and clinical trials of Mahonia species used in TCM based on scientific literature. Available scientific evidence supporting the therapeutic effects of Mahonia species in TCM is demonstrated and opportunities for future research are discussed to highlight the scientific gaps in our knowledge that deserves further investigation. ⋯ The available scientific references demonstrate that the traditional medical uses of some important Mahonia species in TCM have been evaluated in modern pharmacological studies. Isoquinoline alkaloids may contribute to some of the activities shown by the plants of this genus. However, further studies employing scientific technologies and methods are warranted to reveal the phytochemistry of this genus, particularly to detail the active compounds and the underlying mechanisms.

The genus Anthocleista of the Gentianaceae family contains 14 species of trees and shrub-like plants distributed in tropical Africa, in Madagascar and on the Comoros. Traditionally, they are commonly used in the treatment of diabetes, hypertension, malaria, typhoid fever, obesity, diarrhea, dysentery, hyperprolactinemia, abdominal pain, ulcer, jaundice, asthma, hemorrhoids, hernia, cancer, wounds, chest pains, inflammations, rheumatism, STDs, infertility and skin diseases. They serve as an anthelmintic, laxative, diuretic and contraceptive. This review aims to provide for the first time a repository of ethnopharmacological information while critically evaluating the relation between the traditional medicinal uses, chemical constituents and pharmacological activities of the Anthocleista species so as to unveil opportunities for future research. ⋯ A. djalonensis and A. vogelii are potential antidiabetic and antibacterial agents. The antibacterial potency relates to infections or diseases caused by E. coli, S. typhi and S. aureus such as urinary tract infections, typhoid, diarrhea, skin diseases, and food poisoning. Pharmacological research on this genus is quite elementary and limited, thus, more advanced research is necessary to isolate and determine the activities of bioactive compounds in vitro and in vivo, establish their mechanisms of action and commence the process of clinical research.

The medicinal plant Pterodon pubescens Benth has been traditionally used for a long time to treat rheumatic diseases due to its anti-inflammatory and analgesic activities. The present study aims to evaluate the antinociceptive effect of ethanolic extract from P. pubescens fruits (EEPp) in a model of neuropathic pain in mice. ⋯ Taken together, these results provide the first experimental evidence of the significant antinociceptive effect of EEPp on neuropathic pain without causing side effects, such as sedation or locomotor dysfunction. Moreover, these results appear to be mediated, at least in part, by the inhibition of glutamatergic receptors, TRPV1 and TRPA1 channels and proinflammatory cytokines. Thus, this study adds new scientific evidence and highlights the therapeutic potential of the medicinal plant P. pubescens in the development of phytomedicines for the management of neuropathic pain.
