Management Of Plantar Psoriasis With Homoeopathy: A Case Study


Palmoplantar psoriasis is a chronic, autoimmune disease characterised by the rise of desquamative plaques on the palms and soles. Due to the thick stratum corneum of the palmoplantar regions, the search for effective topical treatments has been significantly more difficult than other forms of psoriasis. A case of 60 years old male suffering from plantar psoriasis here treated successfully within 6 months by a single individualised homoeopathic medicine Arnica montana 30 with minimum repetitions. There was remarkable improvement in a very short period of time. The case was observed for 2 years without recurrence which suggests that permanent cure is achievable through single and simple individualised homoeopathic treatment.

PPP: palmoplantar psoriasis

PPPASI: palmoplantar psoriasis area and severity index


Psoriasis is a chronic, recurring autoimmune disease that triggers the rise of scaly, red lesions on the skin, affecting approximately 2% of the global population. One clinical subtype of psoriasis localized on the palms and soles is classified as palmoplantar psoriasis (PPP). PPP affects approximately 14% of patients diagnosed with psoriasis. Characteristic effects include the formation of scaly erythematous plaques on the palms and soles, accompanied with scaling and keratinization [1]. Resulting lesions from PPP lead to functional impairments in daily activities that cause social and psychological distress. Compared to other forms of psoriasis, the disease’s occurrence on the palms and soles causes a significantly greater decrease on patient’s quality of life [2]. Interleukin 17 (IL-17) plays a significant role in the pathogenesis of this variant of psoriasis compared with other forms of psoriasis. Patients with PPP treated with systemic biologics targeting IL-17 tend to have favourable results [3]. Studies have attributed PPP to stem from physical activity involved in occupation. External factors correlated with manual labour, stemming from interactions with friction and mechanical stimuli, cause psoriatic lesions to become localized in pressure bearing areas [1,4].

The palmoplantar psoriasis area and severity index (PPPASI), is a point-based system quantifying the area and quality of PPP. The PPPASI measures erythema, induration, and desquamation on a scale of 0-4, 4 being the most severe. The PPPASI score is widely used as a measure of improvement in many clinical studies. Some studies, however, will not refer to the PPPASI, but will measure similar symptoms using a point-based scoring system [5].

Following is a case of plantar psoriasis treated successfully with homoeopathy. Her informed consent was taken.

Provisional diagnosis

Plantar psoriasis [6]

Totality of symptoms:

  • Dry, scaly patches on both soles of foot
  • Dry, scaly eruptions with itching, aggravated at night
  • Dry, scaly eruptions with burning
  • Dry, scaly eruptions aggravated by least touch
  • Pain in both knees
  • Pain aggravation by walking and ascending stairs
  • Aversion to milk
  • Intolerance to alcohol causes diarrhoea
  • Sleep disturbed due to itching
  • Desire for solitude when angry
  • Over sensitiveness to pain

Rubrics [7]:

  • mind – sensitive – pain, to
  • extremities – pain – beaten, as if
  • extremities – pain – knee – ascending stairs, on
  • skin – eruptions – burning
  • skin – eruptions – itching – night
  • skin – eruptions – psoriasis
  • skin – eruptions – symmetrical
  • generals – food and drinks – milk – aversion

Analysis of the case:

After analysis and evaluation of the case, the characteristic symptoms were used to form the totality, “dry, scaly eruptions on both soles of foot accompanied by itching at night and burning, aggravation by least touch, pain in both the knees as if beaten were some important particulars of the case”. “Aversion to milk, intolerance to alcohol causes diarrhoea were important physical generals” and desire for solitude and over sensitiveness to pain were included in the mental generals.  

The selection of the remedy was based on the repertorisation from RADAR 10 software [7] using Synthesis treasure edition, 2009 by Frederick Schroyens with repertorial result showing top five remedies as Arnica montana, Sepia officinalis, Silicea terra, Belladonna and Natrum muriaticum from which Arnica montana scored highest covering all the eight rubrics.


Arnica montana 30/ 4 doses

Basis of prescription:

After analysing the reportorial result and consultation with Boericke’s Materia Medica [8] and Allen’s Keynotes [9], Arnica montana 30 was prescribed (including symptoms such as over sensitiveness to pain, dry scaly eruptions on both soles of foot associated with sensation of itching and burning, aversion to milk, pain in bilateral knee joint with sensation as if beaten, etc). Arnica montana was selected on the basis of bilateral symmetry of the complaints as stated in the Boericke’s materia medica [8].  Arnica montana 30 was given in 4 doses after which the patient showed slight improvement followed by placebo. The prescription was repeated every month according to the condition of the complaints for six months followed by placebo.

Potency: Third to thirtieth potency. Locally, the tincture, but should never be applied hot or at all when abrasions or cuts are present.

Follow Up:

20-08-2019 Patient Ist visit Arnica montana 30/ 4 doses (“The dose of medicine (of the first prescription) that acts without producing new troublesome symptoms in to be continued while gradually ascending, so long as the patient with general improvement, begins to feel in the mild degree the return to of one or several old original complaints”.) (Aph 248,280) [10]
19-09-2019 Improvement in scaly eruptions and itching Placebo
21-10-2019 Reduction in the dry scaly eruptions but itching and burning persisted, Pain in knee persisted     Arnica montana 30/ 3 doses (According to Kent’s 11th observation, reappearance of older symptoms and the improvement is standstill then the repetition of the remedy should be prescribed) [11]
19-11-2019 Further improvement in eruptions and itching, pain in knees relieved Placebo
22-12-2019 Reduction in the number of eruptions, itching and burning relieved Placebo
18-01-2020 Slight improvement in eruptions itching persisted   Arnica montana 30 / 2 doses
19-02-2020 Eruptions are relieved with clean skin over soles with no associated complaints Placebo
20-03-2020 No eruptions persisted Placebo



Discussion and conclusion:

Homoeopathic medicine selected on the basis of principles of homoeopathy proved to be very effective in this case of plantar psoriasis and shown good results of improvement. Arnica montana was selected on the basis of bilateral symmetry of the symptoms, sensation as if beaten in extremities, physical and mental generals keeping in mind the materia medica and homoeopathic principles. Treatment was continued for 6 months. There was marked improvement after the first prescription continued with placebo for 1 month. Next dose of Arnica was given after 1 month when the improvement became standstill. The doses were repeated after observing the condition of the complaints and progress in the condition of the disease. The patient was observed for 3 years to see if there is any relapsing of the complaint.

The potency selection was done on the basis of susceptibility of the patient as stated by Dr Close [12]

1. The greater the characteristic symptoms of the drug in the case, the greater the susceptibility to the remedy and the higher the potency required.
2. Age: medium and higher potencies for children.
3. Higher potencies for sensitive, intelligent persons.
4. Higher potencies for persons of intellectual or sedentary occupation and those exposed to excitement or to the continual influence of drugs.
5. In terminal conditions even the crude drugs may be required
He also mentioned, “different potencies act differently in different cases and individuals at different times under different conditions. All may be needed. No one potency, high or low, will meet the requirement of all cases at all times.”
