Tentacles of Condylactis gigantea were exposed successively to H2O?NaASW dilutions, isosmotic 1 mol/l MgSO4?NaASW mixtures and returned to H2O?NaASW dilutions to explore the possible isotonicity of isosmotic MgSO4 and the reversibility of the effects of this solution on the ionosmotic characteristics of the tentacles.
The strongest sleeping pills (sedative-hypnotics) are typically some of the quick-acting barbiturates such as secobarbital (Seconal), pentobarbital (Nembutal) and amobarbital (Amtyl). However, these are very old hypnotics and they are highly dangerous. It is very easy to overdose on them and they are highly addictive.
The two best natural sleep aid treatments are valerian and melatonin. Valerian is a sedative herb that has used for centuries to address insomnia. You can find standardized extracts in health food stores and pharmacies. Take one to two capsules a half hour before bedtime.
