Alloxan – It's Toxicologic Pathology And Homoeopathic Utility

Alloxan is a lesser-known Homoeopathic remedy mainly used for the treatment of Diabetes Mellitus. In other schools, this chemical inorganic compound is used to induce Diabetes Mellitus in experimental rats for research purposes. This article is a collaborative study on the animal studies and Homoeopathic proving conducted on Alloxan to understand the toxicologic pathology of Alloxan and utilization of this knowledge in the field of homoeopathy as guides in Homoeopathic provings.

Alloxan or Alloxan hydrate is an organic compound with formula C4H2N2O4. Alloxan is a member of the class Pyrimidone, with a structure similar to that of perhydropyrimidine. The anhydrous derivative is also known as a dimeric derivative. These are some of the earliest known organic compounds.

As it is a hyperglycemic agent and metabolite, it shows a variety of biological activity.

IUPAC name:  5,5-dihydroxypiramidine-2,4,6(1H,3H,5H)-trione

Other names:  5,5-dihydroxybarbituric acid

Physical property:

The acidic compound formed by oxidation of Uric Acid, isolated as an efflorescent crystalline hydrate. The anhydrous crystals are yellow coloured, rhomboid prisms soluble in alcohol and insoluble in water. It becomes colourless when hydrogenated. Alloxan stains skin purple due to the formation of murexide.


Alloxan was originally obtained by oxidation of Uric Acid by Nitric Acid. Can be prepared by oxidation of barbituric acid by chromium trioxide. The dimeric derivative alloxantin can be prepared through partial reduction of Alloxan with hydrogen sulfide.


Toxic pathology:

Alloxan is a toxic glucose analogue, which selectively destroys insulin-producing B-cells of the Islets of Langerhans in the Pancreas. This results in the development of Insulin Dependent Diabetes Mellitus also called as ‘Alloxan Diabetes’ which resembles Type 1 diabetes in pathophysiology and histology.

Alloxan is toxic to B-cells due to its accumulation in uptake via the GLUT2 glucose transporter. This is the presence of intercellular thiols generates reactive Oxygen species in a cyclic reaction with Dialuric Acid as a reducing product. This redox reaction resulting in the formation of superoxide and hydroxyl radicals make alloxan toxic to B cells. It reduces glutathione, an antioxidant capable of preventing damage to cellular components caused by reactive Oxygen, due to its high affinity to SH- containing cellular compounds. Also inhibits glucokinase, an SH-containing protein.


Alloxan has a toxic effect on the hepatic and renal cells too. Recent researches conducted by Japanese Society of Toxicologic Pathology shows that Alloxan causes Acute Tubulo-intestinal nephritis. It initially causes degeneration of the thick ascending limbs of Henle and induces mitochondrial and cellular damage in the tubular epithelium. This consequently results in Nephrotoxicity.


Animal studies conducted shows that administration of Alloxan results in the increase of DNA per liver cell nucleus. Histopathology shows hepatic sinusoidal enlargement, micro and micro hepatocyte fatty degeneration with progressive structural loss and steatohepatitis with periportal fibrosis. The decrease in the number of intracytoplasmic organelles, degeneration of mitochondria, rough endoplasmic reticulum and nucleus.

Homoeopathic utility: Alloxanum/ Alloxan


Alloxan was discovered by Dum abd his collaborates in 1943. Homoeopathic proving of Alloxan was done by WL Templeton twice, in 1949 on 6 subjects with potencies 6C & 30C and in 1951 on 9 subjects and 7 controls.

Sphere of action:

Pancreas, Kidney, Liver, Lung, Blood


Alloxan causes rapid degeneration of the B-cells of the islets of Langerhans, which is responsible for the production of Insulin. This is done either by inhibition of enzymatic processes (proteins of Thiol group SH) or by affecting the chelating power of Zinc known for the intercellular fixation of Insulin.

According to Dr Hahnemann in aphorism 110, toxicological symptoms, though cannot be considered as a homoeopathic symptom, helps us to improve upon the symptomatology of less proven remedies and will thereby help us to validate symptoms, understand its possible sphere of actions and pathophysiology. Studies like this were animal proving and human proving are collaborate analyzed, lesser-known and less proven remedies can have more authentic symptomatology.
