From what I’ve gathered recently, steam distillation was more of a field extraction to test on site. Most have been using solvents to grab more terpenes, rather than boil.
From some of our extractions, some have a real cannabis smell and others have a sulfuric note that is present in the vape when vaped.
Most essential oils on plants with higher terpene profiles will always use solvent.
We ended up buying the Lab Society kit, but we need a more gentle boil.
