Deep blue-In case of asphyxiant poisons and aniline .
Bright red - In case of CO poisoning.
Cherry red - In case of HCN poisoning .
Dark brown or yellow - Phosphorus .
Deep cynosis - With opium and cardiac poisons .
Early rigor mortis - With dstrychnine.

5. Cont...
 Early appearance of the sign of decomposition - With H2S gas .
 Detectable smell - in case of volatile poisons , opium and HCN, KCN or NaCN
 Hemorrhagic spots under the skin and mucus membrane : Phosphorus.
 Ulceration on lips , angles of mouth - Corrosive poisons.

6. Cont…
 Stain near mouth , on hands - HNO3 and CuSO4.
 Blood tinged froth from mouth and nose - Organophosphorus compounds.
 Alopecia, hyper pigmentation and hyperkeratosis - Ch. Arsenic poisoning
 Staining , erosion and ulceration near the female external genitalia - Use of abortifacient agents
or torturing agents .
 Injection marks - Injection of poisons (snake bite or otherwise)

aspects of lips, mucus membrane of mouth and tongue - Corrosive agents, g soft, swollen, sodden,
translucent, bleached tongue and mucus membrane of mouth - Corrosive alkali n. Hardening of the
lungs - Phenol. Yellowish - Blueish at nitric acid - Copper sulphate n Carbonization and charring -
Conc. Sulfuric acid

hydrocarbons, opium, cyanogen, formaldehyde, phosphorus;
 Detectable liquid - kerosene.

10. Cont…
Small intestine - May show ulceration, perforation sometimes

 Kidneys - Swollen, reddish, soft, sometime greasy in touch with haemorrhage in calyces and other |
degenerative changes - mercury, 0xqlic acid | Carbolic acid, phosphorus, cantharides, viper snake

and the calyces.
 Urinary bladder - Haemorrhage in cases of Abreus. preceptories, viper snake bite, cantharides
poisoning

12. Cont…
 Larynx and trachea - Hyperaemic, inflamed - In cases of inhalation of irritating gases leaking of
corrosive agents while ingestion vomiting; froth in the lumen of trachea and larynx in case of opium
and organophosphorus. Poisoning
 Chest Cavity - Smell of volatile poisons, cyanogen's, opium etc. can be detected
 Lungs - Voluminous, congested, presence of Tardieu's spots - In case of asphyxiants and inhaled
poisons. Cut section gives blood stained frothy - fluid in case of opium | and other asphyxiants

13. Cont…
• Heart - Subendocardial haemorrhagic spots in cases of arsenic, phosphorus, mercuric chloride etc.
• Brain and spinal cord - Congestion and oedema. Brain - may be congested, oedematous with
occasional haemorrhagic points at places - asphyxiant poisons.
• Uterus and vagina - Staining, congestion haemorrhage, ulceration in cases of attempted abortion by
