Styptic Powder is still widely used & often added to bird first aid kits but there have been cases of parrots dying after being applied. In other cases of using styptic powder the parrots have ended up with tissue burn & death & toxicity. Styptic powder inhaled by humans can irritate the respiratory system.
A safer & much cheaper solution to using Styptic powder is cornflour. Cornflour is natural, very cheap & just as effective as Styptic powder but without the side effects.
It is also said that cornflour & aloe gel together is even more effective. Aloe has great anti-bacterial properties & helps the cornflour to stick. Aloe can be applied directly to the broken feather or nail & cornflour applied directly after.
