This has been answered before and the answer is no.
No no and no their has never been eph in lick it was used in chicken feed to help hens lay in colder months however this has been taken out as far as I am
Zero. There are no salt blocks available on the market that have ephedrine in them.
Nowhere because no such salt or mineral block exists.
You cannot because you are looking for something that doesn't exist.
There really is no such salt block or mineral mix. You can check with your veterinarian or those companies that make livestock salt blocks but it's highly likely you will not find such an ingredient in salt licks for cattle.
None. No such salt block or loose mineral mix exists.
More difficult than you can imagine, simply because no such salt block is known to exist (except among crystal meth drug addicts who find various ways to make crystal meth...)
None. No such salt block, medicated block nor loose mineral mix exists.
None because no such block exists.
What is the prose's to extract salt from salt lick?
There are no salt or mineral nor medicated mineral blocks that contain any form of ephedrine in them. Sick animals are treated by antibiotics via injection, not by just giving them a "medicated" salt block.
Good for livestock and wildlife, not for people.
Cattle usually will lick themselves to scratch an itch or remove flies off of their bodies. Another term for lick could be the salt lick, this is a block of salt or minerals that the cattle will lick, it just gives them extra nutrients.
