That is interesting what you said about the drugs used in Mountain Dew. From frequenting the Iodine forum I've learned that Bromide has been increasingly added to the food supply over the past many decades. It's added to flours as well as all sorts of processed, packaged foods, and in many cases is literally sprayed onto produce to help give it a "showroom finish". One of the doctors who's researched Iodine deficiency discovered along the way that Bromides, when taken in regular and excessive amounts, will eventually collect in the CNS - central nervous system, where it can then be the source of all kinds of problems, including mental disorders, seizures, depression, and all manner of deranged behavior. BVO - brominated vegetable oil, is the form used in soda pops as well as Gatorade, especially those that feature an artificial "citrus flavor"..... "is it IN you?"
Due to the laws governing "food information labels", it's becoming difficult to really know when a given product DOES contain Bromide. Mt Dew seems to be one of the few pop producers that still includes this info on their label. Most flours are brominated, and most of these DO NOT indicte so on their label. The only way to know is sort of like reverse psychology - if the label does not mention anything to do with Bromide, this usually means the product contains bromide. If the label indictes "does not contain bromide", then you know, and there are relatively very few brands who make commercially available non-brominated flours.
As to Lobelia, reading right from Christopher's SoNH guide, among it's therapeutic actions are relaxant (expecially in larger doses), anti-spasmodic and expectorant. "As a powerful anti-spasmodic, lobelia causes immediate relaxation and expansion of any contracted parts of the respiratory system, such as bronchial tubes, esophagus, glottis and larynx".
