Bothrops lanceolatus
Animal
Bothrops Lanceolatus is suited to broken-down, haemorrhagic constitutions in septic states with great lassitude and sluggishness. The characteristic patient shows thrombotic phenomena including hemiplegia, aphasia, and haemorrhages from multiple orifices, with symptoms following a diagonal course.
Key symptoms
- Haemorrhages from every orifice of the body; black spots
- Hemiplegia with aphasia; inability to articulate without tongue involvement
- Great lassitude and sluggishness; broken-down haemorrhagic constitution
- Diagonal course of symptoms
- Day blindness; amaurosis from haemorrhage into retina
- Black vomiting; intense haematemesis
- Swollen, livid, cold skin with haemorrhagic infiltration and gangrene
- Nervous trembling; septic states
Worse (aggravation)
- Right side

Yellow Viper (BOTHROPS LANCIOLATUS - LACHESIS LANCIOLATUS)
Its venom is most coagulating, (also Lachesis). We should expect to find under these remedies the symptomatology of thrombosis, also thrombotic phenomena, as hemiplegia, aphasia, inability to articulate (Linn J. Boyd).

Relationship
Compare: Toxicophis.--Moccasin Snake (pain and fever recur annually, after bite from this snake, and sometimes change location with disappearance of first symptoms. An unusual dryness of skin follows the bite. Œdematous swellings and periodical neuralgia. Pain travels from one part to another). Other snake poisons, notably Lachesis.
Trachinus,-Stingfish (intolerable pains, swelling, acute blood, poisoning, gangrene).

Sixth to thirtieth potency.

Yellow viper. Vipera jaune. Fer-de-lance of the island of Martinique. N. O. Crotalidæ. Solution of the poison in glycerine; attenuations in rectified spirit.

Blindness. Bones, necrosis of. Day-blindness. Gangrene. Hæmorrhages. Lungs, congestion of. Tongue, paralysis of.
Characteristics
The most peculiar symptoms of Bothrops, for which Ozanam is the authority, are these: Amaurosis. Day-blindness.─"can scarcely see her way after sunrise." Inability to articulate without any affection of the tongue. Hæmorrhages, the blood being fluid and black. All the symptoms of pulmonary congestion, oppressed breathing and bloody expectoration, more or less profuse. Paralysis of one arm or one leg only. After being bitten in the little finger of one hand, paralysis began in the finger-tips of the other hand and extended over the whole of that side. Deep gangrene, bones laid bare and necrotic. Intolerable pain in right great toe (patient bitten in left thumb). The diagonal course of symptoms is marked. Hemiplegia. Dissecting gangrene. Slight shivering followed by very profuse cold sweat.
