AbstractAn overview is given of the current position of medicinal herbs in general in relation to usage, market and production, types of pharmacological activity and how they differ from conventional drugs. The increasing importance of quality and manufactured products is also discussed. A more detailed consideration of these issues is given in relation to echinacea, valerian and St John's wort as these herbs are well studied, are market leaders and have widespread community usage.

Clinical isolates of Candida yeast are the most common cause of opportunistic fungal infections resistant to certain antifungal drugs. Therefore, it is necessary to detect more effective antifungal agents that would be successful in overcoming such infections. Among them are some herbal products and their active constituents.The purpose of this review is to summarize the current state of knowledge onherbal products and their active constituents havingantifungal activity against drug-resistant Candida sp. used alone and in combination with antifungal drugs.The possible mechanisms of their action on drug-resistant Candida sp. including (1) inhibition of budding yeast transformation into hyphae; (2) inhibition of biofilm formation; (3) inhibition of cell wall or cytoplasmic membrane biosynthesis; (4) ROS production; and (5) over-expression of membrane transporters will be also described.

Background: In this survey, it was aimed to determine the types of medicinal herbs and herbal products, reasons of use and consciousness levels among the medical students in the first three years of the School of Medicine.Methods: A cross-sectional descriptive questionnaire consisting of 50 questions was applied to all the students in the first three years of Dokuz Eylül University School of Medicine between September 1, 2016 and June 1, 2017.Results: The results of 571 participating students were evaluated. Of these students, 301 (52.7%) were females and 270 (47.3%) were males. It was found that 73.4% (n=419) of the students used these products for treatment and mostly consumed linden, sage tea, mint and rosehip. Also, 11.6% of the students had chronic diseases (n=66). It was determined that 69.7% (n=46) of these students having chronic diseases used medicinal herbs and herbal products. Only 12.0% of the students had an opinion about the legal regulations regarding the use of herbs and herbal products in Turkey, while 39.7% of them had no idea, and 48.3% stated that such regulations on this matter were unreasonable. However, 59.7% of the respondents stated that legal regulations were necessary. It was found that the participating students used herbs and herbal products generally for therapeutic purposes without having sufficient knowledge about medicinal herbs; therefore it was necessary to increase their level of consciousness.Conclusions: Medical students neither have adequate medical information about medicinal herbs and herbal products, nor about the regulations on these products. It is crucial to revise the courses in the medical education so that the students would get informed about the regulations as well as potential risks of herbal plants while still in the medical schools.

Eriodictyol is a flavonoid that belongs to a subclass of flavanones and is widespread in citrus fruits, vegetables, and medicinally important plants. Eriodictyol has been anticipated to explain the method of its activity via multiple cellular signaling cascades. Eriodictyol is an effective natural drug source to maintain higher health standards due to its excellent therapeutic roles in neuroprotection, cardioprotective activity, hepatoprotective activity, antidiabetes and obesity, and skin protection and having highly analgesic, antioxidant, and anti-inflammatory effects, antipyretic and antinociceptive actions, antitumor activity, and much more. This review aims to highlight the modes of action of eriodictyol against various diseases via multiple cellular signaling pathways.
