“…But polycythemia also increases blood viscosity, the less beneficial results of which are fatigue and headache (Weinreb and Shih 1975). Fuchs' (1978) study of hematocrit values in a sample of Andeans suggested that coca chewing decreased red blood cell counts and blood viscosity, and thus alleviated the effects of chronic polycythemia without affecting other responses such as increased lung capacity and vessel dilation.…”

“…Los datos también permiten sugerir que los síntomas subjetivos que acompañan el mal de montaña crónico (4) sean muy similares a los que ocurren en la depresión (6,7), por ejemplo, fatiga fácil o sensación de falta de energía física y mental, tristeza, irritabilidad, alteraciones del sueño (insomnio, hipersomnia). Es interesante que ancestralmente se hayan combatido los síntomas del MMC con hoja de coca (16). La cocaína actúa bloqueando y disminuyendo el transportador de catecolaminas (17), precisamente el receptor que se ha encontrado incrementado en la hipoxia crónica experimental (14).…”

“…Occasionally, plant use in the past can be discussed in a novel way in relation to stress, as in the case of coca chewing in the Andean area of South America. One view put forward is that coca alkaloids have an effect on erythropoiesis and high altitude tolerance (Fuchs 1978). There is no doubt that there are physiological adaptations in peoples living in high altitudes (Pugh 1966), as a consequence of long-term stress in the Andes, but it is far too simple to claim a close relationship between coca chewing by peoples in the past and the overall stresses of life in these high altitudes (Bray and Dollery 1983).…”
