The "Borneol" valerates are another class; they are as follows:
New-Bornyval, borneol isovaleryl glycolate. It passes the stomach undecomposed, and hence it is not irritating. Used in the neuroses, as is valerian.
The dose is from 4 to 12 minims, in milk or coffee, after meals.
Gynoval, the isovaleric acid ester of isoborneol, is used as is oil of valerian. It comes in 4-grain pearls, one or two being given after meals. Larger doses may be given safely and with little disturbance.
