lysergic

Used in the designation of lysergic acid and lysergic acid diethylamide: produced by hydrolysis from ergot.

Much more soluble in water than ergotoxine, ergotamine, sensibamine or ergoclavine, and is thought to be the hydroxyisopropylamide of lysergic acid.

In a series of papers during the past few years Jacobs and [Lyman C.] Craig have shown that the ergot alkaloids are derivatives of a unique acid base, lysergic acid, in which the latter or an isomer is conjugated with certain amino acids or substances which can be derived from them, such as 2-aminopropanol-1, pyruvic acid, and isobutyrylformic acid. Since lysergic acid is thus the common characteristic constituent of these alkaloids, the determination of its structure became at once a major issue in the ergot alkaloid problem.

Psychedelic, trippy.

The Doves' mantras of desolation are even trippier than the first couple Cranes records (though maybe not as lysergic as prime Swans or Ravens), […]

As mentioned earlier, my first impression of the sleeve art was that it bore marked similarity to a poetry collection – nothing very lysergic about that.
