Similar to their US counterparts, Costa Rican women enter menopause at ∼50 years of age, have similar symptoms, including hot flashes and night sweats, as well as an overall negative attitude toward the menopausal transition. One study of rural women in Monteverde reported that women knew little about the menopausal transition, as the subject was not discussed. Similar to other Latin American women, the use of hormone therapy by Costa Rican women is low and instead they use alternative therapies, including massage, dietary changes and herbal medicines...

Cancer patients use herbs in spite of severe interactions risks with major anticancer drugs. In daily practice, it is very difficult for oncologists to detect and define the risk of a herb-anticancer drug interaction (HDI). In this work, we realised a state of play in one of the most populated region of France by evaluating, through a specific questionnaire, the position of a representative panel of oncologists. About 80% of them thought that herbs interact with anticancer treatments whereas only 15.4% of them actually knew the real HDI...

Great progress has been made in the fight against disease in many different fields of medicine, especially in the field of natural medicine. Phytoestrogens and related compounds play a major role in the prevention and treatment of cancer. Chemoprevention, a narrative approach for controlling cancer, involves the use of specific natural products or synthetic chemical agents to overturn, repress, or prevent pre-malignancy before the development of invasive cancer. Several natural products confer protective effects against a wide range of cancers; examples include grains, nuts, cereals, spices, fruits, vegetables, beverages, medicinal plants, herbs, and their various phytochemical constituents including phenolics, flavonoids, carotenoids, and nitrogen-containing and organosulfur compounds...

BACKGROUND/OBJECTIVES: The evidence of possible roles for the most common hot infusions intake (tea and coffee) in the risk of colorectal cancer (CRC) needs additional data. Regarding 'mate' intake (infusion of Ilex paraguariensis herb), a previous multi-site study reported lack of association for its highest intake on CRC risk. The present study was conducted to better understand the associations between the intake of this and other infusions and CRC risk. SUBJECTS/METHODS: Patients (611 CRC incident cases and 2394 controls, all belonging to public hospitals) were interviewed through a questionnaire, including socio-demographic, reproductive and lifestyle variables, and a food-frequency questionnaire of 64 items, analyzing tea, 'mate' and coffee intake (consumer status, daily intake, age at start and at quit)...

Renal cell carcinoma (RCC) is a common urinary malignancy that is resistant to chemotherapy and radiotherapy. Osthole, a monomer compound extracted from a traditional Chinese herb, has potent anti-tumor effects on various types of cancer cells. However, the therapeutic effects of osthole on RCC remain unclear. In our study, osthole could suppress the proliferation and colony formation of two RCC cell lines, ACHN and 786-O cells, in a dose-dependent manner. Treatment with osthole resulted in a significant, dose-dependent increase in the expression of pro-apoptotic proteins (cleaved caspase-3 and Bax) and decreased expression of anti-apoptotic proteins (Bcl-2 and survivin), which were consistent with evidence of apoptotic nuclear morphology revealed by DAPI staining...

Osteosarcoma is the most common primary bone cancer in children and adolescents. In spite of aggressive treatment, osteosarcoma has a high mortality rate with minimal improvements in survival over past few decades. Polyphyllin I (PPI), a component in the traditional Chinese medicinal herb Paris polyphylla Smith, has been shown to have anti-tumor properties. However, its mechanism as an anti-osteosarcoma agent has not been well elucidated. In this study, we found that PPI suppressed osteosarcoma cell viability, arrested cell cycle in G2/M phase, induced apoptosis and inhibited invasion and migration of osteosarcoma cells...
