The effects of Curcuma longa and curcumin on reproductive systems. Curcumin, the active component of C. Th e attempt of the present review was to give an effort on a detailed literature survey concentrated on the protective effects of C. Reflections about Osteoarthritis and Curcuma longa.
Osteoarthritis OA is a chronic inflammatory degenerative process that affects joints such as the hands, hips, shoulders, feet, spine, and especially knees in 20 ejemplos de preposiciones yahoo dating of people worldwide. Some authors have shown that Curcuma longa components may exhibit benefic effects in the treatment of degenerative diseases as OA. This plant belongs to the family Zingiberaceae and it is popularly known as turmeric or saffron.
This review intended to perform a retrospective search to identify studies involving humans and animal models. This review was based on articles linking OA and C. Databases as Medline, Science Direct, and Lilacs were consulted and a retrospective search was carried out in order to identify studies involving humans and animal models. The curcuminoids from C. They also act as inducer of apoptosis in synoviocytes, decreasing the inflammation process and may also reduce the synthesis of reactive oxygen species.
For these reasons, new pharmaceutical technology and pharmacological studies should be proposed to determine the dose, the best delivery vehicle, pharmaceutical formulation and route of administration of this plant so its use as an adjunct in the treatment of OA may become a reality in clinical practice.
The search terms were "testis" or "ovary" and "Curcuma longa ", "curcumin", "antioxidant effect", "anti-inflammatory effect" and "anti-cancer effect". Therefore, different effects of C. Effects of Zingiber officinale, Curcuma longa and Alpinia galanga Effects
