Mercury group of homeopathy remedies

Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.

The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.


  1. Mercury dissolves gold, silver, natrum and kali.
  2. It is used in amalgam fillings (a mixture of mercury, silver, tin and zinc).
  3. It is also used in mercury switches,-aligner and -batteries, as well as in barometers, thermometers, blood pressure gages, lights and ultra violet lamps.
  4. Agriculture- manufacturing bactericides, pesticides

The provings of quicksilver, or metallic Mercury, and the Soluble Mercury of Hahnemann have been separately placed in Allen’s Encylopaedia, but according to Farrington  no essential differences between them. Mercurius solubilis is not a pure mercurial preparation. It contains some Ammonia and some Nitric acid. There are only traces of Nitric acid, however, and yet these traces must modify its symptomatology somewhat, but to what degree he doesn’t know. The provings of the “solubilis” are excellent. They are complete, much more so than those of the “vivus.” These latter are collected more from poisoning cases and from clinical cases than from actual provings. If, then, the symptoms are clearly placed in the Encyclopedia under Soluble Mercury, he advised to use that preparation.

Mental features

1) Destructiveness, elusiveness and restlessness are 3 grand features of Hg

2) Essence- position of power is being threatened. Struggle is an active process Struggle followed by exhaustion- compared to acidums

3)Fight is the theme till decomposition occurs- both mentally & physically

4) Exaggerated power: tyranny
They want to hold to to power at any cost, but they feel they are being threatened. This makes them overreact in an effort to maintain control. They become dictatorial and will not tolerate any contradiction or insult. Their thirst for power turns them into real tyrants, using the techniques of: ‘divide and rule’.

5) Exaggerated responsibility
The responsibility for their task is very important to them. They feel they are the only one who is capable of taking this on and they dare not hand over to anyone else out of fear that it might all go wrong. That is why they get so angry when someone takes over without asking them first. They are also hard workers, can be workaholics.

6) Suspicious
Their exaggerated control and dictatorial behaviour doesn’t make them very popular. There are enemies all over the place and they don’t know who they can trust anymore.  The only way to cope is by planning all sorts of intrigues themselves. It is a typical picture of paranoia.

7) Manipulation– trying to mislead other people so they can remain in control.

Repeating old strategies as a means of holding on to power

Repeating tricks to hold on to power: manipulation

8) The decline of the empire – strategies and tricks no longer it is working – gradual decay- in physical level also- in the form of ulcers, caries, syphilis etc

9) isolated by enemies- attacking him- but no courage to attack them because of fear of death— which results in trembling of hands, voice- stammering.

10)Betrayal is the strong theme of mercury. They are mistrustful

10) Failure state- feels that he had committed a crime

11) sexuality- sexual maturity at an early state-perverted desires

Physical features

1) Locality: right.

2) Perspiration: profuse, agg. night, stinking, putrid, aggravates – non relieving sweat

3) Time modality: agg. 9 pm, agg. night (3).

4) Congestive:

  • Merc is basically inflammatory group of remedies.
  • Every inflammation begins with congestion and Merc has it forcefully in its pathogenesis.
  • This congestiveness has to be differentiated from Aco, Bell or Ferr-ph.
  • These three drugs have congestion in their first stage of inflammation.
  • Merc presents a furtherance of activity where suppuration has supervened.
  • An abscess in Merc is of spreading congestion-more red, more painful, more throbbing, and with adjacent lymphadenopathy.

5) Catarrhal:

  • Merc causes inflammation of mucous membranes resulting in profuse, thin, slimy, acrid, burning, foul or thick greenish-yellow discharges.
  • Merc covers simple to malignant catarrhs in its pathogenesis.

   6)  Exudative:

  • Exuding the ichorous fluid, pus etc. through affected lesions like boils, abscesses, carbuncles, sinuses, fistulae etc. is the characteristic of Merc.
  • The exudation is usually offensive in nature.


  •  Merc has ulcerations; of the mucous membranes, esp. of mouth and throat.
  •  The syphilitic miasmatic dimension is responsible for recurrent and non-healing ulcerations; ulcers based on deep pathologies, or metabolic basis. Syphilitic phagadenic ulcers.

 8)  Destructive:

  • Merc transformshealthy cells into decrepit, inflamed and necrotic wrecks.
  • Merc is destructive both at body and mind levels.
  • Its lesions resemble those of syphilis.
  • Merc’s action is similar to that of the toxins of infectious diseases.
  •  Inflammations of malignant types, and prostration.
  • Appropriate Merc salt can be thought of in cases where perforation threatens

   9)  Glandular: 

  • Merc has increased glandular activity, esp. of salivary and mucous glands produces increased salivation.
  •  Lymphatic system is esp. affected with all the membranes and glands.
  •  Merc has concomitant lymphadenopathy with skin lesions like boil, abscess, ulcer etc.
  • Syphilitic miasm is responsible for even malignant glandular affections and fevers.
  • Based on scrofulous diathesis, it also covers tubercular glandular affections. Chronic suppurating glands; cold abscesses are dealt with Merc.

10) Scrofulous:

  • Tuberculous disease of lymphatic nodes and of bone, with slowly suppurating abscesses.
  •  Merc decomposes the blood, producing a profound anemia.
  •  It thus affects the nutrition and prepares a ground for scrofulous affections.
  •  Syphilitic activity further leads to cachexia.

 11) Scorbutic:

  •  Merc has spongy and bleeding gums.
  • When the general condition is impaired and metabolism affected because of malnutrition, scorbusis may get developed.
  • Scorbusis may be a precursor of metabolic diseases like DM.

 12) Anaemic:

Merc through decomposition of blood, and through bone-narrow depression causes profound or aplastic anemia.

  •  Hemorrhages, metabolic disorders, hepatic and renal toxicity cause anemia.
  •  Hence Merc constitution is emaciated, pale with dark ring around eyes.

 13 . Rheumatic:

  • Rheumatic diathesis is one of the features of Merc group.
  • It has both acute and chronic dimensions.
  • Mercs are sensitive to both heat and cold – human barometers and they come down with acute joint swellings and pains consequent to weather changes. ‘Redness’ indicates Merc.

14) Offensive

  • Merc is filthy, mentally as well as physically.
  • All discharges smell horribly.
  • The decomposition, the debris, the slough, the suppuration; smell emanates from the body.
  • Mercs are, hence, recognized to an observant physician.

 15. Sensitive 

 Mercs are very sensitive to weather changes, hence termed as ‘human barometer’.

  •  The inflamed part is very sensitive and depicts all characters of inflammation.
  •  The reactivity pattern is exhibited well.
  •  Sensitivity attracts environmental stimuli; hence modalities or sensory stimuli / inputs are usually available.
  • Sensitivity is also present at mind level.

16) Tremulous

  • ‘Trembling’ is a marked characteristic of Merc. Paralysis agitans – Parkinsonism –come under pathogenetic action of Merc.
  • Syphilitic expressions with a lot of pathologies at nerves, spinal cord, and brain resulting in inco-ordination are responsible for tremulousness.

 17)  Dropsical:

  • Dropsy due to anemia, hepatic, renal  or cardiac affections are covered by Merc.
  • Edematous swellings in the affected parts characterize Merc.

18)  Agile

  • Merc is basically an‘active’ group.
  • We get rapid development of symptoms leading to destruction.
  • When active disease processes are present, Merc group is indicated.
  • It is less indicated for remnants or for exhaustion stage.
  • That work is allotted to other groups like Carbon etc. Usually full-blown acute or chronic diseases are found in Merc group because of increased sensitivity and susceptibility.

 18. Chaotic

  • The aberrant immune response as expressed in autoimmune disorders give the character of chaos.
  • Under severe infection, the system becomes prey and behaves in an eccentric way.
  • Tubercular miasma actively dominates the scene.
  • The agile character allows the system to go into chaos.

19. Debilitated

  • The sway of disease processes under tubercular and syphilitic miasmatic activities depletes the energy.
  • The system can’t continue for long and succumbs.
  • Anemia, malnourishments add to the state of debility.
  • Discharges produced do not ameliorate and further deplete the energy.

20)  Syphilitic

  • Merc and syphilis are knot together since antiquity.
  • Merc has in its pathogenesis all stages of syphilis-primary, secondary and tertiary.
  • Low states and phagadenic condition from syphilitic poison.
  • Destructive effects on nerves.
  • It covers both acute and chronic phases.
  • Discharges which system develops as defense do not help and syphilitic march is continued.

21) pains– burning and throbbing pains

22) A/F- Suppression of  discharges, abuse of crude mercury, bad affects of sugar, stings, vapors of arsenic or copper, suppressed syphilis, winter diseases.

  1. Merc personality disorganized mind as that of a criminal with slime in mouth and stools tongue never dry,TREMOR of mind and body all actions too hasty or too slow foul breath heavy sweating no relief,classical homeopaths make use of remedy in high potency to clean imbecility and create will power.Merc cor is serious merc sol with tenesmus burning urethera so lies with knees drawn up.Merc Dulc creates pallor pale scrofulous flabby bloated constitution.sores ulcers is clinical use of merc but deep issue is removal of TREMOR a sort of preparing to cause damage to others or in turn may lead to own damage say if sudden seize of heart is there he may die.old era homeopaths were concentrating to repair mind which in turn cause of ulcers etc.iod is blended with merc in glandular involvements,thus MERC is natural cure of a criminal types which policing may not reform.

  2. Gibson Miller says check of thermal reaction is imp example MERC in acute case is worse by heat in chronic case worse by cold,this doctor enlighten us cold and hot remedies,but one not mix thermal reactions acute and chronic on same platform,like calcarea constitution is chilly easy perspiration,sulphur hot constitution is throwing out toxins morbid material via skin with foul odor,hepar constitution is chilly but perspiration is foul odor like sulphur.selection of remedy in acute case is entirely different as from chronic case do not mix.violent chill sudden cytokine storm lachesis is indicated but hidden pus somewhere in body giving chronic toubles crotalus works as taught by ML Tyler.

  3. MERC,mucous membrane swelling with acrid secretion tendency to form ulcers with gray base,comparatively belladona inflammation is sudden acute red with dryness.merc major sign is foul breath due to decomposition of mucus saliva plus sticky perspiration give no relief colors linen yellow,swollen lymph glands but without pain whereas bella hepar there is pain.urethera rectum inflammation shown by tenesmus pain.merc neither tolerate hot drink nor cold drink so cellulitis if not tolerate heat case is for bella or hepar.merc dulc best foe enlarged liver,neck glands merciod merc cyan for diphtheria and stomatitis merccor.lower potency helps ripen inflammation then drain out and high potency aborts suppurations all this depends on vital force.after redness of belladona is over merc comes to picture.hepar comes to use for handling staphylcoccus type infections.oldera homeopaths advise treat by symptoms there is no name of disease.merc is patent for halitosis pyorrhoea imprint of teeth on tongue due to swelling aggravation symptoms nightly trademark for syphilitic miasm.
