Oak Gall for Vaginal Tightening and Rejuvenation
Oak Gall (Quercus Infectoria) is a plant or shrub native to Asian countries that have certain phytochemical contents that beneficial for women's health and general health as well.
The extract of this shrub is very rich in Tannins, and this phtyochemical content can be obtained when the leaves infested by Cyrips gallaentinctoria wasp.

Effect of Tannins in the female genital organ is, it can constrict the vaginal wall and vaginal tissues. In medicine, this effect is known as Astringent properties (ref).
Interestingly, the leaves that have been infested by wasp also causes several chemical reactions which is further found an ability to kill or inhibit the growth of harmful bacteria (fungi, bacterial, viral).
All of these effects have been well documented in pharmacology as the source of properties for astringent and antimicrobial in addition to anti-inflammatory, anti-diabetics, and local anesthetic due to other phytochemical contents isolated from this shrub (gallic acids, ellagic acid, piperonylic acid ester, antioxidants, calcium, fiber, vitamin A and C, iron, carbohydrates, and some proteins).

Overall, as this shrub contains lot of Tannins, making this botanical source as the most potent botanical source for women who want to tight their vagina.
Historically, the words of Tannin derived from the Celtic word for Oak tree, which is given due to containing certain agents that can constrict the tissue and able to render skin collagen impervious to degradation.
In other words, over the time, age, and frequent of sex, the vaginal wall become thin due to decreased collagen expression in the vaginal tissues, making the vagina lose its elasticity and firmness.
Imagine when the collagen in your skin decreased... what will it be? wrinkle, loose, dry, and some other structure degradations.

That's why, the benefits of Oak Gall for female organ referred as natural vaginal rejuvenation as it has an ability to rejuvenate vaginal wall, including to vaginal muscles due to its estrogenic activities.
Unfortunately, many descriptions appeared to public about vaginal rejuvenation is a symmetrical form of vaginal lips like teen and narrowing vaginal hole which eventually suggesting to women for surgery like Vaginoplasty and Labiaplasty.
Narrowing vaginal hole also can be obtained in natural way by increasing collagen production to the vaginal wall for more thick, elastic and tight, and constrict the vaginal tissues. This what we call natural vaginal rejuvenation.
This is completely different from surgical procedure which cut the vaginal wall in order to narrows the hole but as surgeon associations said, this process also cut lot of nerves in the vagina which is eventually making the women experienced with numbness or loss of sensitivity. In fact, this negative effect can be permanent while other women reported need years to feel the sensation again which they suspected 'the nerves have been reconnected'.

Therefore, women who want to tighten up and rejuvenate their vagina naturally and safe, Oak gall is one of the best answer.
This is what V-Tight Gel offers to women as the product also contain Oak gall. More than that, it also contains extract of Witch Hazel which in medicine also well documented have strong astringent properties that can make the vagina tissue tighten. In fact, with this combination of formula, the tightness sensation can be felt in few minutes after application.

In addition, as explained before, Oak gall also have antimicrobial properties which is beneficial for vaginal health.
At least 2 studies have shown these properties. One study from Department of Biomedical Science, Universiti Kebangsaan Malaysia published in the Indian Journal of Pharmacology 2005;37:26-9, said "Our findings were also supported by other researchers who reported that the crude powder of the galls of Q. infectoria was found to be active against S. auerus and B. subtills while both the methanol and aqueous extracts were active against S. epidermis."
Other studies from Department of Pathology, Faculty of Medicine, Prince of Songkla University, Thailand, published in the journal of electron microscopy (Tokyo): 2009 Oct;(58(5):315-20
