A special kind of water found only on the 2nd planet, Glacia, found in the Markab Star System. It is not widely known off the world but the Andorian's who colonized the world have known it to posess incredibly healing powers when dealing with parasites in the body.
Tydracuclae is a particular chain of water molecules held together by hydrogen bonding, thus it has to be kept very cold (just above freezing) or the chain will break apart. Even though science has scanned this substance, it has been impossible to replicate it. Replicating the water molecule chains cause the chains to break down immediately upon the replication process being done.
Healing Properties
The chain of molecules acts like a toxin to the nervous system of parasites and prevents them from absorbing water from the hosts blood stream, starving it of oxygen or any other nutrients that the water brings into the body.
