Tannic Acid, Reagent ACS, High Purity, 100 Grams

I bought this product to add to an in-grown toe-nail product called Outgro, which used to work until the FDA forced them to take out the Tannic Acid. I put this product into a bottle of Outgro I had bought, and now it works just like it used to. Also, this was the fastest delivery I have ever gotten from a seller on Amazon! I was very pleased because I really needed this product, and I didn't have to pay for expedited shipping.

Our shepherds paw would not heal totally for about a year. We used this on advice from our Vet and it healed in about a month. We needed to cover with a protective tape but it worked its magic!

Used for a science experiment and it did the job.

Worked well for aging wood

Item as described, fast delivery, no problems. Supplier should have included a Safety Data Sheet.

I have an aggravating ingrown toenail and since the medicine Outgrow was forced to change its formula I've resorted to self treatment. Tannic acid was the main ingredient in Outgrow so this product is a natural choice for the purpose and it works. Mixed 10 to 1 with distilled water and dailey application with a cotton swab and it does the trick.

Fresh, pure. Preserves dry collodion plates like a champ.

bought it for my grandson for ingrown toenail. comes with no instructions how to use or mix.he has had some relief using it but it is not a miracle cure.
