ABSTRACT Although Chrysanthemum indicum Linné (Compositae) has long been used in traditional Korean, Chinese, Japanese medicine to treat various immune-related diseases the underlying mechanism(s) by which these effects are induced remains to be defined in vivo model system. We investigated the effects of 70% ethanolic extract from Chrysanthemum indicum Linné (CIE) on skin inflammation in mice.
Production of pro-inflammatory cytokines (TNF-alpha and IL-1 beta), activation of myeloperoxidase, and histological assessment were examined in acute and chronic skin inflammation using 12-O-tetradecanoyl-phorbol-13-acetate (TPA)-induced mouse ear edema.
CIE inhibited topical edema in the mouse ear, following administration at 200mg/kg (i.p.), leading to substantial reductions in skin thickness and tissue weight, inflammatory cytokine production, neutrophil-mediated myeloperoxidase activity, and various histopathological indicators. Furthermore, CIE was effective at reducing inflammatory damage induced by chronic TPA exposure.
These results demonstrate that CIE is an effective anti-inflammatory agent in murine phorbol ester-induced dermatitis, and suggest that the extract may have therapeutic potential in a variety of immune-related cutaneous diseases.

    ABSTRACT: Herbal medicines have been used in preventing and treating skin disorders for centuries. It has been demonstrated that systemic administration of chrysanthemum extract exhibits anti-inflammatory properties. However, whether topical applications of apigenin, a constituent of chrysanthemum extract, influence cutaneous inflammation is still unclear. In the present study, we first tested whether topical applications of apigenin alleviate cutaneous inflammation in murine models of acute dermatitis. The murine models of acute allergic contact dermatitis and acute irritant contact dermatitis were established by topical application of oxazolone and phorbol 12-myristate 13-acetate (TPA), respectively. Inflammation was assessed in both dermatitis models by measuring ear thickness. Additionally, the effect of apigenin on stratum corneum function in a murine subacute allergic contact dermatitis model was assessed with an MPA5 physiology monitor. Our results demonstrate that topical applications of apigenin exhibit therapeutic effects in both acute irritant contact dermatitis and allergic contact dermatitis models. Moreover, in comparison with the vehicle treatment, topical apigenin treatment significantly reduced transepidermal water loss, lowered skin surface pH, and increased stratum corneum hydration in a subacute murine allergic contact dermatitis model. Together, these results suggest that topical application of apigenin could provide an alternative regimen for the treatment of dermatitis.

    ABSTRACT: The aqueous fraction (AF) of an ethanolic extract from Chrysanthemum indicum was evaluated for analgesic activity in mice using chemical and thermal models of nociception. Given orally, AF at doses of 300 and 600 mg/kg produced significant inhibitions on chemical nociception induced by intraperitoneal acetic acid, subplantar formalin/capsaicin injections and on thermal nociception in the tail-flick test and in the hot plate test. In the pentobarbital sodium-induced sleeping time test and the open-field test, AF neither significantly enhanced the pentobarbital sodium-induced sleeping time nor impaired the motor performance, indicating that the observed analgesic activity was unlikely due to sedation or motor abnormality. In a measurement of core body temperature, AF did not affect temperature within 80 min. Moreover, the effective dose (600 mg/kg) also showed no toxicity within 7 days. These results suggested further that AF produced analgesic activity possibly related to the flavonoid glycosides and phenolic glycosides in this fraction.

    ABSTRACT: This study was undertaken to evaluate the effect of essential oil from seeds of Zizyphus jujuba on TPA-induced skin inflammation in experimental mice. Exposure of TPA on the ear of the BALB/c mice caused a marked increase in both ear thickness and skin water content. The ear thickness was measured for TPA-induced ear was 0.54 mm, as compared to control (0.23 mm). Treatment with 1% and 10% of essential oil caused significant decrease in ear thicknesses which were measured to be 0.30 and 0.35 mm, as well as reduce the water content about 51% and 53% in the TPA-induced skin inflammation model, respectively. Furthermore, histological analysis clearly confirmed that Z. jujuba essential oil inhibited the inflammatory responses of skin inflammation in animal model. Therefore, our findings demonstrate that the essential oil of Z. jujuba seeds might accelerate the development of new drugs for various inflammatory diseases.
