<s>[INST] I just inhaled one or two sunflower seeds and began coughing for about 15 min. Coughing now subsided and lot of phlem finally came up. Produced by lungs? I did not sense seed coming up in my throat and the sensation of it there is still prevalent. Now what? Drinking water and having yogurt has soothed throat. Thanks. [/INST] Hi, the best way to cure allergy is avoidance of it but if u had already feeling coughing type allergic response to flowers then u can take antihistamines or mast cell stabilizers or steroids as we are not suppose to prescribe medicines here, so I have mentioned only groups of that particular Chat Doctor. There is nothing serious as most of this kind of allergy subsides by itself after 1 or 2 hours. </s>
