Interesting as I just read on this very topic: "That's a misrepresentation because according to Ayurveda, if something is not poisonous, and is taken it moderation, it cannot be harmful to everyone. Cucumber can be harmful to some people, depending on their constitution. According to Ayurveda, the body is made up of differrent components, and different foods have the same components. Since, cucumber and yogurt have high water components, raita can be harmful to someone who has a deficiency of fire component, and beneficial to someone who has overabundance of fire component. I would rather say that Ayurveda is careful about mixing cucumber with yogurt because the mixture can be potent." Shanti/Mary-Anne
