Yuzu Sour RSO Tincture

A liquid cannabis extract in a dropper bottle or with an oral syringe. A tincture is traditionally made with alcohol; however, most tinctures sold today use an oil base, commonly MCT (coconut-derived) oil. Most are made with distillate unless the listing names another extract. The label gives milligrams per milliliter (mg/ml) and per bottle, and the dropper is marked for measuring.

A tincture can be taken two ways:

1. A tincture dose held under the tongue (sublingual) for about a minute. Some of the dose is absorbed through the lining of the mouth, and effects may begin in 15 to 45 minutes.
2. Swallowed, acting like an edible. Effects begin in roughly 30 minutes to 2 hours.

In practice, part of a sublingual dose is swallowed too, so many people get a mix of both.

Rick Simpson Oil (RSO) and full-extract cannabis oil (FECO) are whole-plant extracts. RSO/FECO are made by soaking cannabis in a solvent, then evaporating the solvent until a thick, dark, tar-like oil remains. FECO is usually made with food-grade ethanol. The original RSO method, popularized by Canadian Rick Simpson in the early 2000s, used harsher solvents such as naphtha or isopropyl alcohol. Today, menus use the two names for the same product. You can use RSO/FECO orally, sublingually, or topically.

On a menu, "Sativa" signals the effects the seller expects: energizing, uplifting, felt more in the head, suited to daytime. As with Indica, that is tradition and not a measured property.
