Insecta are invertebrate animals – without back bone – and are included in arthropods. Arthropoda is the largest, most dominant group and includes about 80% of known animal species. They are capable of flying.
Entomology refers to study of insects. Insects are grouped in the kingdom under phylum arthropoada & the class insecta.
PHYLUM : ARTHROPOADA
CLASS : INSECTA
Man had started the use of insects and insect products since time immemorial even at the cost of animal’s life. Insects have been under use in human civilization since prehistoric period as mentioned in our religious literatures like Vedas, puranas , the ramayana, mahabharat and charka samhita. Some foreign travelers like Fahiyan and whenson had also discussed the use of insects and insect’s product as medicine.
As far as Homeopathy is concerned insects have a major role in the preparation of medicines.

Functions as haptens that form immunogenic conjugates host proteins. Life threatening anaphylactic response of a sensitized human appears within minutes after administration of specific antigen and is manifested by respiratory distress often followed by vascular collapse or by shock without antecedent respiration difficulty.
cutaneous manifestations : Pruitus and urticaria with or without angioedema. Localized, non-pitting, angioedema may occur which may be asymptomatic or cause a burning or stinging sensation.
Gastro intestinal manifestations: Nausea, vomiting crampy abdominal pain and diarrhoea.
Respiratory system: Manifestations laryngeal edema, experienced as a lump in the throat, hoarseness or strider. Bronchial obstruction is associated with a feeling of tightness in the chest of audible wheezing. Angioedema of the epiglottis and larynx and to some extend in the hypo pharynx and trachea, causes mechanical obstruction and death.
Cardiovascular system: Manifestable visceral congestion with a loss of intravascular blood volume leads to vascular collapse and death.
