BACKGROUND The effects of butterbur (BB), a herbal remedy, as add-on therapy to inhaled corticosteroids in patients with atopic asthma is currently unknown. OBJECTIVE We evaluated the effects of BB, given as add-on therapy to asthmatic patients maintained on inhaled corticosteroids, assessing

OBJECTIVE To elucidate the anti-allergic and anti-inflammatory effects of Petasites genus, we studied the effects of several compounds isolated from Petasites japonicas leaves. METHODS Bakkenolide B was isolated from Petasites japonicus leaves. Antigen-induced degranulation was measured in RBL-2H3

The Korean Petasites japonicus is a perennial plant used in folk medicine as a remedy for many diseases and popularly consumed as spring greens. Ten polyphenols were characterized from the leaves, stems and roots of this plant via high-performance liquid chromatography-tandem mass spectrometry.

Two new aryltetralin lactone lignans, petasitesins A and B were isolated from the hot water extract of the leaves of butterbur (Petasites japonicus) along with six known compounds. The chemical structures of lignans 1 and 2 were elucidated on the basis of 1D and 2D nuclear

The methanol extract from Clerodendrum petasites S. Moore (CP extract) was assessed for anti-inflammatory and antipyretic activities on the experimental animal models. It was found that CP extract possessed moderate inhibitory activity on acute phase of inflammation in a dose-related manner as seen

Previous studies have suggested that histamine and leukotrienes (LTs) play an important pathobiological role in IgE-mediated allergic diseases. In vitro studies suggested that an extract of Petasites hybridus (Ze339) blocks LT synthesis in monocytes and granulocytes. Petasins are considered to be

A large production of leukotrienes (LTs) can be induced in human eosinophils or neutrophils by priming with granulocyte-macrophage colony-stimulating factor and subsequent stimulation with platelet-activating factor (PAF) or the anaphylatoxin C5a. Here, we investigated the effects of a plant extract

With the worldwide rapid increasing interest in the use of natural products as dietary supplements, medical remedies and functional foods, it has been accepted that omitting the plant constituents with potential adverse effects was a huge fault of the past. Several countries developed regulations to

S-petasin, a kind of sesquiterpene ester, is the anti-inflammatory ann analgesic component of the butterbur (Petasites hybridus). The clinical benefit of S-petasin is the spasmolytic activity, but its side effects on the reproductive endocrinology are not clear yet. The present study was to explore

For hundreds of years butterbur (Petasites hybridus) has been used against many diseases. Modern indications are the prophylaxis of migraine, tension headache, spasms of the urogenital tract, gastro-intestinal tract and bile duct and hopefully hay fever and asthma in the near future. The petasines,

Calcitonin gene-related peptide (CGRP) is a pivotal messenger in the inflammatory process in migraine. Limited evidence indicates that diet impacts circulating levels of CGRP, suggesting that certain elements in the diet may influence migraine outcomes. Interruption of calcium signaling, a mechanism

Petasites hybridus (Common butterbur) is extensively used in traditional medicine, and is currently gaining interest and popularity as a food supplement and for its medicinal properties. It contains a large number of active compounds of potential therapeutic activity, but also toxic

To explore the anti-allergic and anti-inflammatory effects of extracts of Petasites genus, we studied the effects of s-petasin, a major sesquiterpene from Petasites formosanus (a butterbur species) on asthma and peritonitis models. In an ovalbumin-induced mouse asthma model, s-petasin significantly

BACKGROUND The giant butterbur Petasites japonicus is used to treat asthma and allergic diseases in traditional Korean, Japanese, and Chinese medicine. OBJECTIVE To elucidate the anti-allergic effect of Petasites genus, we studied effects of several compounds from Petasites japonicus leaves and

OBJECTIVE To study the anti-inflammatory and antioxidant effects of Petasites tricholobus and its phenolic components. METHODS Phenolic compounds were separated purified by column chromatographic methods such as macroporous resin D-101, silica gel, ODS, MCI GEL CHP 20P, Sephadex LH-20. Their
