Kalopanax pictus is known as Castor-Aralia or Prickly Castor-oil tree. K. pictus extracts have been used for dietary health supplements and are an important area in drug development with numerous pharmacological functions in East Asia; however, their pharmacological functions have not been introduced in Western countries. This paper briefly reviews the most relevant experimental data on the pharmacological actions of K. pictus to overcome the lack of information on this plant. K. pictus extracts have proved to be effective in the treatment of inflammation and were shown to have a number of pharmaceutically relevant benefits that include anti-rheumatoidal, hepatoprotective, anti-diabetic, anti-cancer effects, etc. There are a few known active pharmacological components such as kalopanaxsaponin A and I. Although the molecular mechanisms of most of the effects are not fully understood, major mechanisms seem to involve the interplay between active components and signaling mediated by phosphorylation events during stress adaptation.
Key words: Kalopanax pictus, araliaceae, Kalopanaxsaponins A, anti-inflammatory, anti-rheumatoidal activity, anti-diabetic, hepatoprotective effect.

Abstract
Background: Taraxacum officinale (G.H. Weber ex Wiggers), commonly known as dandelion, is a herbaceous plant native to North America, Europe and Asia. This plant has been used for health purposes since ancient times. The phytochemicals present in different parts of the plant are responsible for its medicinal properties. In this review, we describe the main health properties of Taraxacum officinale.
Main body of the abstract: We searched for the main medicinal properties of Taraxacum officinale in the scientific literature, using the PubMed database. We selected 54 studies and we described twelve therapeutic properties, which are reported in previous studies. These properties are diuretic, hepatoprotective, anticolitis, immunoprotective, antiviral, antifungal, antibacterial, antiarthritic, antidiabetic, antiobesity, antioxidant and anticancer effects. We also found that the most frequently reported therapeutic effects include hepatoprotective, antioxidant and anticancer activities.
Short conclusion: In this review, we describe the medicinal properties of Taraxacum officinale reported in previous studies. Antioxidant, hepatoprotective and anticancer effects are mostly found in the scientific literature.
Keywords: Taraxacum officinale, Dandelion, Medicinal properties, Hepatoprotective, Antioxidant, Anticancer.

Summary
Biofilms are communities of bacteria, fungi or yeasts that form on diverse biotic or abiotic surfaces, and play important roles in pathogenesis and drug resistance. A generic saw palmetto oil inhibited biofilm formation by Staphylococcus aureus, Escherichia coli O157:H7 and fungal Candida albicans without affecting their planktonic cell growth. Two main components of the oil, lauric acid and myristic acid, are responsible for this antibiofilm activity. Their antibiofilm activities were observed in dual-species biofilms as well as three-species biofilms of S. aureus, E. coli O157:H7 and C. albicans. Transcriptomic analysis showed that lauric acid and myristic acid repressed the expressions of haemolysin genes (hla and hld) in S. aureus, several biofilm-related genes (csgAB, fimH and flhD) in E. coli and hypha cell wall gene HWP1 in C. albicans, which supported biofilm inhibition. Also, saw palmetto oil, lauric acid and myristic acid reduced virulence of three microbes in a nematode infection model and exhibited minimal cytotoxicity. Furthermore, combinatorial treatment of fatty acids and antibiotics showed synergistic antibacterial efficacy against S. aureus and E. coli O157:H7. These results demonstrate that saw palmetto oil and its main fatty acids might be useful for controlling bacterial infections as well as multispecies biofilms.
