why most researchers talks only about the plants of high altitude? Is there any significance or relation between the value/ effectiveness of the plant species to its location/altitude?
The curative properties of the medicinal plants are owing to the presence of various complex chemical substances of different composition present as secondary metabolites. The plants growing on high altitudes are exposed to more stressful conditions hence they synthesize greater number and amount of secondary metabolites to cope up the stressful conditions. Probably this is the reason that plants found on high altitude are more researched in terms of medicinal value.
