The alternative treatment of this disease with plants and their derivatives is a common practice around the world, especially in Latin America. There are several clinical studies, in vivo or in vitro that focus on assessing the hypoglycemic capacity of various plant products used empirically by the population for years for the phytotherapeutic treatment of the disease, as well as the chemicals related to the mechanism of action that produces this hypoglycemic effect. The aim of this article is to briefly review the evidence of the hypoglycemic capacity of some plant products for the alternative treatment of type 2 diabetes. Keywords: Hypoglycaemic capacity, phytochemicals, phytotherapy, type 2 diabetes Resumen: La diabetes tipo dos es una enfermedad que se caracteriza por la presencia crónica de niveles elevados de glucemia provocado por un defecto en la secreción de insulina o en la acción de dicha hormona en el organismo la cual debe ser tratada integralmente con un enfoque multidisciplinario. El tratamiento alternativo de esta enfermedad con plantas y sus derivados es una práctica común alrededor del mundo, especialmente en América Latina; existen diversos estudios de tipo clínico, in vivo o in vitro que se enfocan en evaluar la capacidad hipoglucemiante de diversos productos vegetales utilizados empíricamente por la población durante años para el tratamiento fitoterapéutico de la enfermedad, así como los químicos relacionados con el mecanismo de acción que produce dicho efecto hipoglucemiante. El presente artículo tiene como objetivo hacer una breve reseña de las evidencias de la capacidad hipoglucemiante de algunos productos vegetales para el tratamiento alternativo de la diabetes mellitus tipo 2. Palabras Clave: Capacidad hipoglucemiante, fitoquímicos, fitoterapia, diabetes mellitus tipo 2 INTRODUCTION the body.1 It is a condition with multiple risk factors such as Type 2 diabetes is defined as a group of metabolic disorders advanced age, obesity, sedentary lifestyle, family history with characterized by chronic increase in blood glucose levels diabetes and socioeconomic level among others; it is of caused by a defect in the insulin secretion or in the action in chronic and complex evolution.2,3 _____________________________________________________________________________________________________________________________ ____________________________ a Autor de Correspondencia, Escuela Superior de Medicina, Instituto Politécnico Nacional, "Unidad Casco de Santo Tomas".

For this, there Diagnosing the disease in a timely manner is important, must be the presence of several hyperglycemia, weight loss, controlling it as soon as possible will help reduce and prevent elevated blood glucose levels despite combined oral complications.7 treatment, decompensation due to ketoacidosis or The criteria used to establish a diagnosis of diabetes are the hyperosmolar state, infections with hyperglycemia, following: pregnancy, glucocorticoid therapy, use of markers as a predictor of a high probability of insulin need.11 • Hemoglobin glucose A1c fraction (HbA1c) > 6.5% PLANT PRODUCTS WITH HYPOGLYCEMIC • Fasting plasma glucose 8 hours > 126mg/dl CAPACITY • Plasmatic glucose two hours after applying a glucose Opuntia spp tolerance test by previously administering an anhydrous glucose load of 75 g dissolved in water > 200mg/dl The cactus (Opuntia spp.) belongs to the cacti.
