Hi Silver List, Did I read this correctly, is the writer inferring that People with Blue Moons have Argyria?
I only briefly perused this posting, however, "Blue Moons" in the Finger Nails have many possible causes besides Argyria. Hypoxia or the lack of oxygen is often manifested in a condition called cyanosis, a blue discolouration. Cyanosis can occur in the fingers, including underneath the fingernails, as well as other extremities (called peripheral cyanosis), or in the lips and tongue (central cyanosis). It occurs when the oxygen saturation of arterial blood falls below 85-90%. Cynanosis is not specifically limited to Mt Everest Climbers and High Altitude Balloonists; individuals with some forms of heart disease, blood conditions, drug side effects, or lung diseases (either Chronic or Acute cases) exhibit this condition as in the following: # Arterial obstruction # Cold exposure (due to vasoconstriction) # Raynaud's phenomenon (vasoconstriction) (a co-worker developed this disease as a result of frost-bite when lost in the wilderness) # Reduced cardiac output (e.g. heart failure, hypovolaemia) # Vasoconstriction (medication) # Venous obstruction (e.g. deep vein thrombosis) # Abnormal hemoglobin levels (blood loss from bleeding ulcer for example) # Bronchospasm # Congenital heart disease # Heart failure # Heart valve disease # High altitude # Hypothermia # Hypoventilation # Lung disease # Myocardial infarction # Polycythaemia # Pulmonary embolism # COPD (Emphysema and Chronic Bronchitis) # Asthma In my 30 years in the health field I saw a quantity of individuals (especially in the elderly, but not limited to the elderly) with blue moons. Needless to say, with a rare exception or two, none of these people had ever taken CS. The one time I required a trip to the ER for anaphylactic shock due to a food allergy, my "moons" were indeed bluish in color, however my fingers were not. This predated my taking Colloidal Silver in any form by 25 years. Best Regards, Steve Foss -- The Silver List is a moderated forum for discussing Colloidal Silver.
