Blue Color Urine
بقول ابن سینا: اخضرآسمانجنی و اخضرنیلجی
According to the Modern Medicine
A little unusual, but yes blue urine is possible. Most of the times it is from something you ate or a medication you are taking, but it could be from a rare genetic disease too.
Medical conditions: “Familial benign hypercalcemia, a rare inherited disorder, is sometimes called “Blue diaper syndrome” because children with the disorder have blue urine. Blue diaper syndrome and Hartnup disease are autosomal recessive disorders in which tryptophan builds up in the gastrointestinal tract, causing bacteria to metabolize it to indole, leading to a buildup of indican in the urine.”Â
Methylene blue: “The intravenous injection of methylene blue produces blue urine discolorations. Likewise, ingestion of a sufficient amount of methylene blue, whether isolated or as a component of other medications, home remedies or supplements can also create blue discoloration.”
Porphyria and Blue urine? “Although porphyria is really a set of eight or more disorders that vary in symptoms, but they all share the common feature of accumulated porphyrins in the body. The word porphyria comes from a Greek word porphyrus, which means purple. And that’s what can happen to urine color. It can turn it into a red or purple urine color, but usually not blue urine. Although some people have trouble distinguishing a difference between some shades of purple and blue, so that would account for some of the confusion that some may think the porphyria causes a blue urine color. True blue-colored urine is quite rare because blue pigment combines with urochrome to produce a green color before excretion of urine. This is the reason for several case reports in which methylene blue turns urine green but surprisingly thousand years ago Avicenna already classify the blue tint as a part of green shades.”
It is worth mentioning that according to Avicenna “both Asmanjuni and Nilji shades of the urine could be indicators of a forthcoming paralysis or convulsion in children. The logic is, in addition to the weakness of their neural tissue, phlegm (the cold and wet humor) in children’s bodies is more than in adults. Accordingly, residues of other parts of the body and even their body phlegm itself could be shed in the neural tissue more easily. Therefore, if this excess moisture becomes viscous, it may result in repletion-caused spasm or convulsion”.
Here are the classic 5 shades of green urine found in Cannon of Medicine.
- Pistachios Green  (Fastaghi )
- Sky Green  (Asmanjuni)
- Emerald Green (Nilji)
- Leek Green  (Korrasi)
- Verdigris Green (Zanjari)Â
