Homoeopathic materia medica contained very vast number of drugs. It includes both, polychrest as well as non-polychrest rare drugs. Polychrest drug having wide range of symptoms, so sometime over prescribed, where as rare remedies are overlooked and not even remembered or known to physician. Rare remedies can be very effective in respiratory troubles, when cases having paucity of symptoms, pathological changes, suppression of ailments or acute exacerbation of chronic complaints.
KEY WORDS: Homoeopathy, rare remedies, respiratory ailments, acute exacerbation
ABBREVIATIONS: e.g. – example, OPD – outpatient department
The respiratory system includes not only the lungs but also the chest wall, pulmonary circulation, and central nervous system. There are three key types of respiratory system physiologic disturbances that occur in varying combinations in different lung diseases: ventilatory function, pulmonary circulation, and gas exchange.
The major classes of lung diseases include obstructive lung diseases (e.g., asthma, chronic obstructive pulmonary disease, and bronchiectasis), restrictive lung diseases (e.g., interstitial lung diseases, chest wall abnormalities, and neuromuscular diseases), and vascular abnormalities (e.g., pulmonary thromboembolism, pulmonary arterial hypertension, and pulmonary veno-occlusive disease).
COMMON RESPIRATORY DISEASES BY DIAGNOSTIC CATEGORIES
Obstructive- Asthma, bronchiectasis, chronic obstructive pulmonary disease, cystic fibrosis, bronchiolitis
Restrictive—Parenchymal- sarcoidosis, pneumoconiosis, idiopathic pulmonary fibrosis
desquamative interstitial pneumonitis, drug- or radiation-induced interstitial lung disease, Asbestosis
Restrictive—Extraparenchymal- neuromuscular – diaphragmatic weakness/paralysis myasthenia gravis, guillain-barré syndrome, muscular dystrophies, cervical spine injury, amyotrophic lateral sclerosis
Chest wall/pleural disease-kyphoscoliosis, obesity, ankylosing spondylitis, chronic pleural effusions
Pulmonary vascular disease- Pulmonary embolism, pulmonary arterial hypertension
Malignancy- Bronchogenic carcinoma (small cell or non-small-cell), cancer metastatic to lung
Infectious Diseases- Pneumonia, tracheitis, bronchitis. 
HOMOEOPATHIC APPROACH WITH RARE REMEDIES
Homoeopathic materia medica consists of medicine prepared from different sources. The pathogenetic effect of some drugs are well known to us which is known as polychrest drugs, but still full action of some drugs are not known to us and also these drugs are not frequently prescribed which is called as rare remedies. The polychrest medicines have wide range of effect where as rare medicines have very specific action on particular disease.
Some indication of rare remedies:
- When one has insufficient data to prescribe a polychrest
- When some time well proven medicines do not produced desirable results than rare remedies can be proved beneficial
- When cases of acute exacerbation of chronic problem
- When cases have paucity of symptoms
- When cases have fewer symptoms
- When medicine can be use for palliative purpose
- Rare remedies are useful especially at time many patient in OPD and not much time to take detailed history for a constitutional remedy
SOME ADVANTAGE OF PRESCRIBING RARE REMEDICES
We can prescribe rare remedies when case taking is not possible, even when patient unable to describe his suffering, cases where pathological symptoms are prominent, relative ask for treatment when patient is not available and when we need quick action.
SOME DISADVANTAGE OF PRESCRIBING RARE REMEDIES
Some time rare remedies are not available in store, range of potency is not available. It might not be provide permanent cure.

Every coin has two sides, so even though there is no permanent cure, we can use rare remedies for respiratory troubles. With the help of indicated rare remedies for respiratory troubles like acute and chronic bronchitis, asthma, pneumonia, fibrosis and many more are rapidly give relief to patient. Rare remedies are beneficial in respiratory troubles, where fewer symptoms, paucity of symptoms and polychrest failed to produce desirable effect. Rare remedies also help to control acute exacerbation of chronic disease. Using rare remedies along with polychrest remedies enhance the scope of homoeopathic field over the disease. Indicated rare remedies not only give relief to patient in acute phase of respiratory troubles, but also reduce the suffering of patient and give strength to fight with chronic disease.
