Gluconolactone

Gluconolactone is a white, odorless crystalline powder which is often used as a skin-conditioner.  Gluconolactone is used to keep skin youthful and healthy.  Many lubricant manufacturers use Gluconolactone to keep a smooth and even consistency in their water based lubricants.

Gingko Biloba

Gingko Biloba is an ancient Chinese herb pulled from the Gingko Biloba Tree.  This product is a common treatment in Chinese medicine.  When added, it is believed that a Gingko Biloba can increase cognitive awarness, sex drive, and memory.  Gingko Biloba is widely used in supplements in the USA.  Gingko Biloba has been used to treat erectile dysfunction for thousands of years.

Gag Reflex

A reflexive contraction that occurs when an object contacts the back of the throat. Biologically, the gag reflex helps to prevent choking and suffocation, as it can clear the airway of food and other obstructions.

The gag reflex may be suppressed with practice or through the use of numbing agents, allowing for “deep throating” during oral sex. When numbing agents are used (common examples include lidocaine, benzocaine, and certain herbal extracts), users must be careful to avoid injury during intense sex, since the numbing effect will prevent nerves from registering pain.

Grapeseed Extract

A substance made from the leaves, sap, and fruit of the grape vine plant. Grapeseed extract (also spelled as grape seed extract) may have some health benefits; some studies show that a fairly large dose of the extract can reduce swelling, and it may have anti-inflammatory and antibacterial characteristics when taken as a supplement.

It also has high levels of antioxidants, and when applied topically, grape seed extract may accelerate the skin’s natural healing processes. However, these benefits are not firmly established, and more research needs to be completed to verify these effects.

Grapeseed extract is used in some lubricants and massage oils for its apparent skin-friendly benefits. It is considered a safe ingredient, although it can cause mild itching in large amounts.

Gamma-Aminobutryic Acid (GABA)

A chemical produced by the brain. GABA plays an important role in the central nervous system. It regulates muscle tension, and some supplement formulas include GABA to provide a calming effect or to promote muscle growth.

There is no evidence to show that GABA supplements can function in this manner. Because GABA needs to cross the blood-brain barrier in order to affect the brain, many researchers believe that supplementation is not biologically possible with the small doses found in most over-the-counter pills. Some users may report a calming sensation due to the placebo effect, although there is not enough research to definitively declare whether GABA is effective in any way.

GABA is naturally produced by the body and is considered a safe ingredient in normal doses.

Glucono delta-lactone (GDL)

An additive used in personal lubricants to maintain a consistent texture and consistency. In its pure form, it is a white powder.

GDL increases the acidity of water-based lubricants, and it can act as a pH-balancing agent or a preservative in some formulas. While it is commonly added to meat and dairy products, it is not derived from meat (in other words, GDL it is a vegan-friendly ingredient). GDL is regarded as a safe substance.

Allantoin / Glyoxyldiureide

A chemical substance created by oxidizing uric acid.

The human body naturally creates allantoin, and the compound is found in a number of botanical extracts. It is commonly used in skincare products as a moisturizer, anti-irritant, and as a smoothing agent.

Allantoin may help to prevent common forms of skin damage including razor burn and acne. It is considered a safe ingredient.

G-Spot

Also known as the Gräfenberg Spot, the G-spot is an area in the vagina that is said to be especially sensitive. Stimulating the g-spot can be pleasurable for some women, resulting in powerful (and often more frequent) orgasms.

The G-spot is said to be located on the top wall (towards the stomach), about 1-3 inches into the vagina. It is bean-shaped, and it often has a rough texture.

While many women report that G-spot stimulation enhances sex, not all women can locate their G-spots, and some do not find stimulation pleasurable. As with all erogenous zones, the G-spot is not exactly the same from person to person.

Some stimulating gels are said to enhance G-spot sensitivity, usually through the use of menthol or another “”tingling”” ingredient. These gels may enhance stimulation by drawing blood flow to the G-spot and by drawing the users’ attention the area.

Grapefruit Seed Extract

An extract created from the seed of the grapefruit plan. It is also known simply as GSE.

Marketed as an antimicrobial (a substance that destroys harmful microorganisms), grapefruit seed extract may kill some bacteria by affecting acidity. Scientific research does not fully validate this claim; some studies have found that GSE does not significantly affect the growth of harmful bacteria. However, there is ample evidence demonstrating the antioxidant properties of the extract.

In lubricants and other sexual health products, grapefruit seed extract is used to prevent yeast infections and other microorganism over growths.
