Regarding Grant Piper's Feb. 27 letter, "So much pain for so little gain": There is a simpler and highly effective treatment for hay fever — nettle (Urtica dioica) tea. I have known very bad cases of hay fever to be alleviated within two hours of drinking it. Just try it and see. As humans, we ingest quite enough chemical rubbish without adding overpriced and unnecessary "shots" to the list.
