Why are picric acid and tannic acid both used as treament for burns?

Picric acid is used to treat burns because it is an antistringent and an antiseptic. As an antistringent it causes contraction of the skin cells.

Tannic acid is used to treat burns because it has some advantages over other treatments. It prevents infection, which is common after burns

Further Explanation:

1. Picric acid  

It is one of the most acidic phenols. Like other very nitrated natural compounds,picric acid is an explosive, hence its primary use. It has also been utilized  in medicine/drug (antiseptic, burn treatments) and dyes.

Picric acid is in the same family of nitroaromatic explosives as trinitrotoluene (TNT). It is no longer used as an explosive because of this type of reaction. A stun inhumane unstable intensify that structures stun delicate touchy salts with metals, (for example, lead) is unreasonably clumsy for most regular applications.

2. How to store picric acid

Picric acid and its derivatives should be stored in small quantities in the original container in a cool, dry, well-ventilated area, away from sources of heat. Picric acidis considered a flammable solid when wet with at least 30% water

3. Tannic acid  

Tannic acid is a polymer of gallic acid particles  and glucose. It the example there are 3 gallic acid molecules, but normally there are about 8. Because there are different molecular structures for tannic acid it would have been better to talk about tannic acids (in plural). Tannic acid will hydrolyze into glucose and gallic or ellagic acid units. Tannic acid is odourless but has a very astringent taste. Pure tannic acid is a light yellowish and formless  powder.

4. Tannic acid also used to treat diarrhea

It is one of the most acidic phenols. Like other highly nitrated organic compounds,picric acid is an explosive, hence its primary use. It has also been used in medicine (antiseptic, burn treatments) and dyes.
