 Ausführungsbeispiele : 
1.   10 kg feinve ; mahlener indischer Tragant   werden durch Absieben auf einem Sieb mit 900 Maschen po Quadratzentimeter zunächst von den grobkörnigen Bestandteilen, dann durch Absieben auf einem Sieb mit 3000 Maschen pro Quadratzentimeter von den   feingepulverten   Anteilen befreit.

   1 kg der so gewonnenen Siebfraktion wird eine halbe Stunde mit einer Lösung von   100 g   Oxalsäure mit 2000 Azeton in einem Mischgefäss   durchgearbeitet.   Sodann wild die überschüssige Lösung abfiltriert und das Pulver bei   600 getrocknet.   
 EMI2.1 
 Kupfernitrat in 100 Teilen Alkohol in einem   Misehgefäss   eine halbe Stunde durchgearbeitet, die   überschüssige   Lösung alsdann abfiltriert und das Pulver bei   600 getrocknet.   Infolge der   Einwirkung   des Kupfernitrats nimmt das Pulver eine blaue Färbung an. 
 EMI2.2 
 Tanninlösung gleichmässig befeuchtet und bei   60    getrocknet. 



   6. 1 kg der nach Beispiel 1 gewonnenen Siebfraktion wird mit 1000 cm3 einer   1 %igen alkoholischen   Lösung von Formaldehyd übergossen und nach kurzem Stehen abfiltrieit.   Der Rückstand whd   bei   600 getrocknet.   



   PATENT-ANSPRÜCHE   :  
1. Verfahren zur Herstellung eines pulverförmigen therapeutischen Mittels zur Wundbehandlung aus trockenen Quellstoffen, insbesondere Tragant, in   Korngrössen   von 0'07 bis   0#5     mm, dadurch   gekennzeichnet, dass den Teilchen durch eine chemische Behandlung unter Ausschluss von Alkalien vorzugsweise bei gewöhnlicher Temperatur eine geregelte Quellgeschwindigkeit erteilt wird, beispielsweise durch begrenzte Einwirkung von Säuren oder andern saueren Stoffen oder Sehweimetallsalzen, insbesondere des Zinks, Zinns, Kupfers, Chroms, oder Oxydationsmitteln, insbesondere Halogenen, oder   Gerbstoffen.

 Embodiments:
1. 10 kg fine; Ground Indian tragacanth are first freed from the coarse-grained components by sieving them on a sieve with 900 mesh po square centimeters, then freed from the finely powdered components by sieving them on a sieve with 3000 meshes per square centimeter.

   1 kg of the sieve fraction obtained in this way is worked through for half an hour with a solution of 100 g of oxalic acid with 2000 acetone in a mixing vessel. Then wildly the excess solution filtered off and the powder dried at 600.
 EMI2.1
 Copper nitrate in 100 parts of alcohol in a mixing vessel for half an hour, the excess solution then filtered off and the powder dried at 600. As a result of the action of the copper nitrate, the powder takes on a blue color.
 EMI2.2
 Tannin solution evenly moistened and dried at 60.



   6. 1000 cm3 of a 1% alcoholic solution of formaldehyde is poured over 1 kg of the sieve fraction obtained in Example 1 and filtered off after standing for a short time. The residue whd dried at 600.



   PATENT CLAIMS:
1. A process for the production of a powdery therapeutic agent for treating wounds from dry swelling substances, in particular tragacanth, in grain sizes from 0'07 to 0 # 5 mm, characterized in that the particles are treated by chemical treatment with the exclusion of alkalis, preferably at normal temperature Swelling rate is given, for example by the limited action of acids or other acidic substances or visual metal salts, in particular zinc, tin, copper, chromium, or oxidizing agents, in particular halogens, or tannins.
