Asthma? Sounds like there is a good chance you have an Ascaris(roundworm) infection. Around 20% of the world's population is infected with Ascaris. Since you claim parasite cleanses haven't worked, have you tried Mebendazole? Mebendazole is given in 6 doses over 3 days for roundworm infection. Since very little is absorbed and it is virtually nontoxic anyway, there is very little risk in trying it. In the US it is by prescription though, but in many other places it is over the counter.
