In homeopathic practice, injury management is one of the most common clinical situations. Among the leading remedies, Arnica and Calendula hold a very important place. Although both are indicated in injuries, their sphere of action, nature of wounds, and modalities differ significantly.
This blog provides a clear, exam-oriented and clinically useful comparison of Arnica and Calendula.
| Point | Arnica | Calendula |
|---|---|---|
| 1. Introduction | Arnica is a well-indicated medicine for mechanical type injuries. | Calendula is a useful medicine for clean cut injuries and suppurating wounds. |
| 2. Causation | Results from blow, fall, contusion, traumatic & mechanical injuries; injuries from blunt instruments. | Clean cut injuries, amputation, surgical operations, lacerated wounds during labour, extraction of teeth, fracture of bones, etc. |
| 3. Sensation | Sore, lame, bruised feeling all over affected parts. | Affected area is sensitive to touch. |
| 4. Pain | Very much painful; sensitive to touch. | Pain is excessive and out of proportion to injury due to probable nerve involvement. |
| 5. Character of Injury | Affected parts become blue & black with extravasation of blood. | Used in all cases of loss of soft parts when union cannot be effected by adhesive plasters. |
| 6. Eye / Internal Effects | Injury to conjunctiva & retina due to coughing with extravasation of blood; sore, lame, bruised feeling in the eye. | External wounds with or without loss of substance; torn & jagged looking wounds; post-surgical wounds to promote healthy granulation & prevent excessive suppuration and disfiguring scars. |
| 7. After Labour | After difficult labour there is soreness of parts with retention or incontinence of urine. | Rupture of muscles or tendons; laceration of perineal tear during labour; wounds penetrating articulations with loss of synovial fluid. |
| 8. Acute Injury Action | Controls haemorrhage; reabsorbs extravasation of blood; prevents suppuration & septic condition; prevents postpartum haemorrhage & puerperal complications. | Exhaustion from loss of blood & excessive pain. |
| 9. Nerve / Special Conditions | — | Traumatic & idiopathic neuroma; neuritis from lacerated wounds; after amputation. |
| 10. Dental | — | Bleeding from extracted teeth. |
| 11. Modalities | Worse from touch, motion, rest, damp cold weather; from lying down. | Worse in damp, cloudy weather. |
