Difference between Naja and Lachesis on the Heart in Homoeopathy
Naja tripudians (Cobra venom) produces a sensation as if the heart were tightly grasped, clutched, or drawn together, with a constricted band around the precordium (1). The pain characteristically radiates from the heart down the left arm and shoulder (1, 2). Symptoms are aggravated by lying on the left side and by mental exertion, grief, or worry (1). It is most often indicated in valvular heart disease, endocarditis, and angina accompanied by marked mental gloom, where the patient has a profound sense of impending death and persistent suicidal ideation, yet fears death (1, 2).
Lachesis mutus (Bushmaster venom) also produces precordial constriction, but the dominant sensation is heat and burning, with marked intolerance of tight clothing around the chest and neck (1, 2). A distinguishing feature is that symptoms progress from left to right and are worse on falling asleep, on waking, and in warm weather or spring (1). Cardiac complaints are commonly seen at the climacteric, in menstrual disorders, and in patients with alcoholic or hemorrhoidal tendencies (1, 2). Mentally, the patient is loquacious, jealous, egotistical, and at times intensely religious (1, 2).
The key differentiator at the heart level is therefore: Naja = “heart is squeezed” in a depressed, suicidal patient; Lachesis = “heart is bursting” in a talkative, jealous patient who cannot bear pressure (1, 2).

Phytolacca vs Lachesis on Throat
Phytolacca decandra
Phytolacca affects glandular structures and is well-indicated in sore throat with pain shooting to the ears on swallowing (1). The throat feels hot, rough, and burning, and the tonsils appear dark red or bluish-red, often with pseudo-membranous exudate (2). The tongue is coated at the back with a red tip, and the patient experiences aching in bones and limbs along with the throat complaint (1,3). Hot drinks aggravate, while cold drinks may soothe; there is a marked tendency for suppuration of glands (4). It is useful in tonsillitis, diphtheria, scarlatina, and phthisical subjects (2,5).
Lachesis mutus
Lachesis is the great left-sided remedy; throat symptoms begin on the left and travel to the right (6). There is a sensation of a splinter, constriction, or choking in the throat, and the patient cannot bear anything tight around the neck — collars, scarves, or even touch (1,7). Pain is often worse from warm drinks and after sleep; the throat looks purplish, swollen, and bluish (6,8). Concomitants include loquacity, jealousy, hot flashes, and aggravation during the climacteric or in patients with a hot, intense temperament (1,7,9). It is also indicated when throat complaints follow suppressed discharges, jealousy, or grief (9).
Key Differentiation
1. Side: Right, or left → right (less marked) (Phytolacca)| Left → right (strong) (Lachesis)
2. Sensation: Burning, aching, hot ball (Phytolacca)| Splinter, constriction, choking (Lachesis)
3. Swallowing: Pain shoots to ears (Phytolacca)| Liquids may hurt more than solids (Lachesis)
4. Throat colour: Dark red, bluish-red (Phytolacca)| Purplish, bluish (Lachesis)
5. Worse: Hot drinks, night (Phytolacca)| Warm drinks, after sleep, tight clothing (Lachesis)
6. Concomitants: Bone pains, glandular swelling, breast involvement (Phytolacca)| Jealousy, loquacity, climacteric, intolerance of touch (Lachesis)
7. Constitution: Phthisical, lean, glandular (Phytolacca)| Hot, dark, intense, left-sided (Lachesis)
Clinical clue: Pain radiating to the ear on swallowing points to Phytolacca; an inability to tolerate a closed collar or tight neck points to Lachesis (1,6,9).
