Confusion can arise from the fact that there may be pharmacological effects masquerading as an ‘allergy’. For example, the headache, flushing, racing pulse and giddiness that can come on after too much caffeine is really a drug reaction, not an allergic one. Obviously individual variations in trigger thresholds make this one sometimes hard to observe. Few people understand the incredible range of pharmacological substances that are to be found in plant substances. Most “green-minded” people think of herbs as kind, nurturing and gentle: wouldn’t hurt anyone, right? But, hey, I like to point out that foxglove, hemlock, opium poppy, marijuana, deadly nightshade and countless plants stuffs are dangerous, even poisonous. “Beware the humble carrot” wrote Richard Mackarness; this innocuous looking vegetable contains a neuro-toxin. Not relevant? I had a patient in the 1980s, a young boy, who had epileptic fits every time he ate carrots or anything from the same food family: parsnip, celery, parsley, dill, fennel, coriander etc.
