Colchicum powder or fluid extract is an important drug in 

 these cases. 



The local treatment consists of massage, rubbing and moulding 

 the swellings with cold water, stimulating liniments, or hot water. 



Try to prevent suffocation by attention to the swellings ; keep 

 nostrils open, or perform tracheotomy. 



Do not cut these swellings, as gangrene is apt to follow. If 

 wounds are present, treat them antiseptically. 



The sero-therapeutical treatment is now being used and good 

 results are being reported.
