Because it is a freaking food supplement, with apparently several benefits:

Description
Food Grade Orange Peel
Protects the Stomach and Esophagus
Stimulates Detoxifying Enzymes

Dietary Supplement!

Jarrow Formulas d-Limonene is a volatile oil steam-distilled from orange peel. d-Limonene is the major constituent of several citrus essential oils (orange, lemon and lime) and naturally occurs in citrus juices. d-Limonene promotes upper digestive health by coating the stomach lining and neutralizing acid. Moreover, d-limonene stimulates both Phase I and Phase II detoxifying enzyme systems.

Suggested Use:
Take 1 softgel per day with or after a meal or as directed by your qualified health care consultant. If persistent stomach upset occurs, discontinue use.

Serving Size: 1 Softgel
Amount Per Serving % DV
d-Limonene (from orange peel oil) 1000 mg *
* Daily Value not established.

Grams into Milliliters: Divide the number of grams by the specific gravity of the substance, to obtain the volume in milliliters.

Limonene at 20 Celsius, or 68 Fahrenheit apparently has a specific gravity of .84-.85

Point being, if theoretically (maybe pushing it here) Limonene can hold 2 grams Dmitrius per 100 ml

One is moving close to the position of achieving safe Limonene supplementation,
and Dmitrius supplementation, at a prescribed recommended serving size of 1 Gram: 1 homemade softgel...
= 35 mg Dmitrius, at the same Time...

How/Why:

1 Gram divided by Limonene specific gravity of .85 = 1.76
One gram Limonene softgel then might contain 1.76 ml Limonene, which could possibly in turn hold 35 mg DMT.
Of course, the softgel would expand a little with the addition of another 35 mg.

P.S. If you read the reviews of Supplemental Limonene you'll notice it seems to have cured some folk of Heartburn!

Some interesting info there, but not sure what you're trying to accomplish.

I have used this same exact Jarrow product. It is high quality. I sliced open one of the softgels and squeezed out the d-limo, and it is clear like GT's d-limo. The reason it is 1000mg per softgel is due to the FDA's prescribed limits. I've never had any problems from ingesting d-limo. My stomach likes it.

Swim likes d-limo due to being food grade and it also means he doesn't have to use nasty Xylene in extractions.

Cleaned my oven!

*smiles wide with thumbs up

Haha, normally things that clean your oven are not also good for your stomach. Here we have something that does both...

^^if you take too much limonene it will make you sick. pure essential oils are not safe in high doses. i have no idea what the safe dose or dangerous dose is but don't think this stuff is automatically safe because its in supplements.

I'm guessing if limonene can clean an oven so well (I concur btw) then it will probably do a good job of delubricating your internals... I wouldn't fancy that much.

What kind of empirical data do you have to substantiate your claims?

If you want to degrease your body organs, then go to the grocery store and buy a can of oven cleaner.

Because most terpenes are lippophillic oily non polar substances is precisely why they have a degreasing effect. It also explains why they can be both cytotoxic towards both human cells and bacteria because they can effect your cell membranes by basically dissolving into them. This can alter cell function and kill it or change the workings of some membrane bound protein or directly bind to the protein and act as an agonist or antagonist.
