The word ‘Krimi’ means ‘worms’ or ‘micro organisms’ in Sanskrit.The drug which kills or destructs the worms in their site is called Krimighna.
Ayurveda explains several varieties of Krimi based upon the size, shape, site, nature etc. Even though each variety of worms has their own method to pacify the Krimighna gana referred here intends to kill the maximum variety of Krimis.
By nature itself all such medicines are deep penetrative, hot in potency and pungent or bitter in character.

Qualities in general and actions of Krimighna gana drugs:
These drugs are bitter or astringent in nature. They usually have the tendency to undergo pungent kind of metabolic change (Katu vipiaka) followed with hot potency.
These drugs are potent anti microbial, anti helmenthic, wormicide, bitter tonics and liver stimulants. Few of the drugs have the ability to restore and stabilize the intestinal flora too.
Therapeutic uses of Krimighna gana drugs:
These drugs can be used in intestinal worms, skin diseases, abdominal pain, fever, blood borne disorders, colic pain etc. In food poisoning and mal digestion cases also they are found to be effective.
Formulations containing Krimighna drugs :
Vidangarishtha, Gandeeradyarishtha, Krimighna kashaya, Raktashodhaka kashaya ,Kottam chukkadi kashaya etc formulations possess the ingredients of Krimighna gana.
Disadvantages of Krimighna gana drugs:
As the drugs of this Gana are hot and strong they are not advisable in diarrhea, severe anemia, intestinal perforation, ulceration etc. In pregnancy and puerperal period also this should be avoided or else it should be administered with caution.
Simple formulations that can be made from the above drugs and their application in routine practice:
Akhuparni alone is used in fresh juice or decoction form in intestinal worms. Likewise Vidanga choorna or its kashaya are also equally beneficial in worms. Fine powder of Kushtha has the ability to check repeated episodes of pin worms by strengthening the gut due to its anti microbial property.
Formulation development opportunities:
Tablets and syrups can be made out of these drugs against the worms. By potentiation (bhavana) technique capsules or medicated powders can also be designed.
If laxatives are also included in the formulation desired therapeutic actions can be obtained as per the need, now a days.
