An aqueous Valerian infusion, Tranquil E can be used to naturally treat anxiety problems, quickly calming a horse for long-lasting relaxation. Whilst it can be administered whenever, it is particularly effective immediately prior to stressful or demanding activities (training/transport).

Withdrawal period

Hi Valerian products were recently added to the "banned" list for horses competing under rules. What would be an approximate "withdrawal period " please?

  • Veterinary Surgeon

I am unable to find the up to date list of FEI detection times but studies show that Valerian is absorbed and eliminated rapidly. A withholding period of 24 h should be adequate for this product although withholding for 2-3 days before competition is a good idea to err on the side of caution.

Once the 5 litre bottle has been opened how long does the effectiveness last?

John Cousins
  • Veterinary Surgeon

This product uses natural preservatives a bit like vinegar. It should remain fully effective for several months, but would degrade in time. This will be a gradual process depending on things like, temperatures, humidity, degree and type of contamination (inevitable to some extent whenever any liquid is taken from the container). I would aim to use it all up within 3 months, but it should last considerably more time than that if you can keep it clean and in a cool, dry place (out of the sun).
