petasites japonicus/抗アレルギー

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 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 anti-allergic effect of total bakkenolides from the rhizome of Petasites tricholobus (BAPT) was evaluated in an ovalbumin-induced allergic rhinitis model in male Wistar rats. The major components of the bakkenolide fraction are bakkenolide-D, bakkenolide-B, bakkenolide-IIIa and bakkenolide-IVa,

The Swiss company Zeller is developing an extract of the plant Petasites hybridus (butterbur) as an antiallergic agent. Petasites hybridus extracts have been known for some time to have therapeutic properties. Zeller's extract is codenamed ZE 339. In in vitro studies, ZE 339 inhibited

The efficacy and safety of the butterbur leaf extract Ze 339 (carbon dioxide extract from the leaves of Petasites hybridus L., 8 mg petasines per tablet) were tested in patients with seasonal allergic rhinitis. In an open postmarketing surveillance study, 580 patients were treated with an average of

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 Petasin (Ze 339) was recently introduced on the market as a potent herbal antiallergic drug for treatment of respiratory allergies such as hay fever. Few clinical studies have been performed so far addressing the clinical effectiveness of Ze 339. OBJECTIVE To evaluate the antiallergic

Abnormal neuroinflammatory responses have diverse roles in neuronal death, oxidative stress and neurodegenerative diseases, such as Alzheimer's and Parkinson's disease. Microglia regulate these responses via molecular signaling cascades that involve inflammatory cytokines and complement proteins.

Petasites japonicus (P. japonicus) is a plant of the Asteraceae family. Its roots and stems have been used for the treatment or the prophylaxis of migraine and tension headache as a traditional Chinese medicine in Japan and Korea. Sesquiterpenoids, lignans, and flavonoids are

The leaves of Petasites japonicus are used for their anti-allergic properties in traditional Korean, Japanese, and Chinese medicine. This study aimed to identify bioactive compounds isolated from P. japonicus leaves. All compounds were assessed for their ability of transcriptional activation,
