Boric acid is an inorganic acid which is mainly available as white odorless powder in crystalline form. It dissolves easily in water. This naturally occurring compound is made up of boron, oxygen and hydrogen. Its chemical formula is H3 BO3. Boric acid and its salt are present in many pesticide products. These products are used to control and kill different types of pests which include algae, fungi, weeds, mites, insects etc.

The products that contain boric acid are available as liquids, powder, pellets etc. Being a mild pesticide, boric acid can kill insects and fungi when they eat it.

It can affect the stomach and nervous system of the insect. Although beneficial as a pesticide, accidental exposure can be poisonous for human beings. The toxicity may depend on the amount of boron present in boric acid and its sodium salts.

Signs And Symptoms Of Boric Acid Poisoning

Boric acid has low toxic effect in humans. The toxic symptoms are manifested after accidental ingestion or if the skin comes in contact with boric acid.

    I am a medical professional and it is a certain fact that very minute amounts of boric acid have completely cured patients of mine that have had Phemfigo Vulgar. Naturally dose and manner of administration should be taken into consideration of each individual patient. Likewise boric acid is extremely useful in combating Lupus and other skin issues and rashes of the face and such as is common with individual with certain allergies.

    My 2.9 years old child accidentally consumed boric acid. When we came to know we took him to hospital. The doctor gave him sucral kid solution and kept him under observation. Since nothing abnormal was noticed in the day we brought him back home in the evening as he is well. Doctor was against discharging him. I am worried whether anything adverse would happen?
