I'm going to present this as "kitchen chemistry" as I feel most people with adequate chemistry knowledge (and equipment) will be able to do it correctly without my help. There are three procedures for DXM extraction that are commonly used: precipitation and filtration, single-phase acid-base extraction, and dual-phase acid-bsae extraction (the "Agent Lemon" process). The first method is by far the least popular because the DXM precipitate is often so fine that it passes through the filter paper.

DXM is a safe and effective cough suppressant ingredient found in over-the-counter (OTC) cough medicines. When used according to directions, products containing DXM produce few side effects and have a long history of safety and effectiveness. Some teens are attempting to get high by taking much larger than recommended doses of DXM in the form of OTC cough syrup, tablets and gel caps. In these high doses, DXM can produce hallucinogenic and dissociative effects. See similar questions...

A cough is the sound made when the lungs suddenly expel air and secretions from the airways. A cough can have many causes but it is usually caused by a viral infection of the upper airways. A cough is a symptom of an infection and a necessary evil. A cough can be your friend serving to rid the windpipe of nasty phlegm. When it keeps the child and family awake at night, it becomes the enemy. The main treatment of a cough is good oral hydration to help loosen the secretions. See similar questions...

Mariandina syrup can be used for infants (as well as adults). It has been specially designed to incorporate a wide range of essential nutrients for children above the age of 3. NB: In the case of adults the tablets are always much better as they have a far wider range of ingredients. See similar questions...

The good news is that the colorie count in BioTears is very small. The primary source of calories is from black currant seed and fish oils. 1604 mg (four gelcaps per day) of this oil combination equals less than 18 calories. The vitamin and mineral co-factors have no caloric count assigned to them. My doctor recommended that I take BioTears along with the new prescription drops, Restasis. Is that appropriate? I have very severe dry eyes. See similar questions...

Extract are created by processing a raw material with a solvent and can be used both in medicine as well as the perfume industry. It is "a solution obtained by steeping or soaking" botanicals (roots, leaves, bark etc.) - in our case it is either oil, water, glycerin or grape alcohol. See similar questions...

This is a small list of some of the things which people have reported were particularly unpleasant, boring, or otherwise unenjoyable. Most individuals who have exercised under the influence of DXM have reported negative effects such as nausea, vomiting, cramping, and a general loss of the more enjoyable aspects of the trip. This seems to become more and more significant with higher doses of DXM. The one exception seems to be swimming, which if done on a first plateau DXM dose can be enjoyable. See similar questions...

Some people have trouble achieving hallucinations on DXM. Here are some suggestions that may be helpful, based on reports I have received (note: none of this should be taken as advice in any way; I'm just passing this along): Place yourself in partial or complete darkness. Most NMDA/sigma agents seem to give the best hallucinations when there is little or no visual input. Close your eyes. See similar questions...

The effects of DXM abuse vary with the amount taken. Common effects can include confusion, dizziness, double or blurred vision, slurred speech, impaired pysical coordination, abdominal pain, nausea and vomiting, rapid heart beat, drowsiness, numbness of fingers and toes, and disorientation. DXM abusers describe different "plateaus" ranging from mild distortions of color and sound to visual hallucinations and "out-of-body," dissociative, sensations, and loss of motor control.

There are currently no adequate prevalence measures of DXM abuse, however, use is estimated to be low compared to other drugs. Abuse of cough medicines containing DXM is characterized as sporadic by the Drug Enforcement Administration. There is little in current teen culture - music, movies, fashion and entertainment - that promotes or even mentions cough medicine abuse. The one exception is the Internet. See similar questions...

All chemical processes in this section require pure DXM. If you do not have pure DXM, you must extract from cough formulae as above (and purify it really well). Most of these processes require significant skill, and access to lab equipment and chemicals. To my knowledge none of this is illegal (but don't take my word on it). Don't fret if your yields aren't as good as specified. Most of the procedures are from the same source (96). This is probably the easiest by far. See similar questions...

BioTears Oral GelCaps were designed by the same inventors that designed Hydro Eye. BioTears reflect the most recent dry eye science. BioTears Oral GelCaps includes anti-inflammatory Vitamin E mixed tocopherols to better stabilizes the Omega 6 and Omega 3 fatty acids included in the formulation. The Curcumin inclusion better inhibits the formation of the inflammatory COX2 enzyme. See similar questions...

Night and Day. TheraTears Nutritionals are designed around the metabolic conversion of plant and fish based Omega 3 fatty acids, which, primarily, convert downstream to the series three prostaglandin (PGE3). Simply said; the Omega 6 GLA series one prostaglandins (PGE1) produced by BioTears Oral GelCaps are far more tear and mucous gland specific than the series three prostaglandins in TheraTears Nutritionals.
