Bromine

BROMINE is a toxic mineral found in seaplants and seawater and widely available in foods especially kelp and alfalfa as well as in mussels and animal glands. The highest concentrations in the human body are found in hair, the liver, lungs, and testis. Deficiencies produced in animals have not officially been linked to any in humans. Bromine ingested as the bromide ion has a low order of toxicity and is therefore not a concern in nutrition. Bromides were used as sleeping aids before the discovery of barbiturates. Not much is known about it, but what is known is that as much as 7.5 mg. can safely be taken -- for whatever the reason remains unclear.

Other names include: bromin, Br, Br- , and element 35.
Deficiency symptoms include: deterioration of brain performance and liver function, mental abnormalities, and a deterioration of adrenals/thyroid/pituitary glands.
Toxicity symptoms include: acne, arm and leg coldness, fetid breath, insomnia, male sterility, headaches, emotional agitation and instability, fatigue, hallucinations, amnesia, confusion.
Inhibitors include: chlorides, salt, and mercurial diuretics.
