The carrageenin foot test was established as a sensitive and reliable assay procedure for determining the anti‐inflammatory activity of inflammatory exudates.

Incubation alone at a temperature above 70° C or with pronase at 37° C destroyed the anti‐inflammatory activity of exudate.

The anti‐inflammatory component of exudate was partially precipitated by 50% ammonium sulphate.

A partial purification process was devised using Sephadex G‐150 gel filtration and DEAE and CM cellulose ion exchange chromatography to obtain at least a 24 fold purification.

Measurements of 11‐hydroxycorticosteroid levels indicated that steroids were not involved in the mechanism by which the exudate produced its antiinflammatory effects.
