What was used as a sleeping pill or sedative in the 1870s?

In the 1870s, one commonly used sedative was chloral hydrate, which was synthesized in 1832. It gained popularity as a sleeping pill due to its sedative effects, often prescribed for insomnia and anxiety. Additionally, opiates like laudanum, a tincture of opium, were also widely used during this period for their calming properties. However, the safety and addictive potential of these substances were not well understood at the time.
