Our plant-based nutraceuticals are vegan-friendly Our plant-based nutraceuticals are vegan-friendly Our plant-based nutraceuticals are soy-free. Our plant-based nutraceuticals are made in accordance with GMP standards.


AcuIntegra’s V-Defence 2 Formula™ complements it’s namesake (V-Defence Formula) and is created to support the immune system during recovery from viral infections.

It is composed of herbal extracts from three plants traditionally used in Traditional Chinese Medicine as antiviral and antibacterial remedies, corroborated by contemporary clinical studies.*

When creating V-Defence 2, we once again balanced the ingredients in accordance with TCM principles. Thus the cold, heat-clearing nature of Chinese gall (Galla chinensis; Wu Bei Zi) and Artemisia annua is countered by a warm-natured ginger extract to allow the formula to gently interact with the GI tract.*


What Does our V-Defence 2 Formula™ contain?

Our V-Defence 2 Formula™ contains:

  • Galla chinensis (Chinese gall, Wu Bei Zi) extract – 250mg
  • Artemisia annua (sweet wormwood, Qing Hao) aerial parts extract – 250mg
  • Zingiber officinale (Ginger, Gan Jiang) root extract – 100mg

It comes in a vegan-friendly cellulose capsue.

What Does the Science Say?

Galla chinensis

Galla chinensis (Chinese gall) are galls on the leaves of the shrub Rhus chinensis (commonly knonw as sumac) which grows in temperate, subtropical and tropical regions including China, Japan, Malaysia, Taiwan and India [1].

Chinese gall has featured prominently in Traditional Chinese Medicine under the name of Wu Bei Zi, where it is considered a heat-clearing herb with salty sour taste. It is associated with the Kidney, Large Intestine and Lung meridians [2].

In its traditional use, Chinese gall has been used to remedy persistent cough, congestion, inflammation, fever and excessive sweating; bloody sputums, burns, hemorrhoids, oral diseases, skin infections and certain cancers [1].

Modern research corroborates many of it’s traditional uses, noting the following mechanisms as described by Djakpo & Yao’s 2010 review [1]:

  • Anti-bacterial activity against, for example, Bacillus subtilis, cereus, Escherichia coli, Enterobacter cloacae, Helicobacter pylori, Staphylococcus aureus, and Streptococcus mutans [1,3]
  • Anti-viral activity against HIV-1 , hepatis C, HSV (type 1 and 2) as well as SARS-CoV [1,4,5,6]
  • Anticancer activity (against prostate and lung cancers and sarcoma to mention a few) and anticarcinogenic properties (e.g. by inhibiting enamel demineralization) [1,7,8,9]
  • Support for anti-inflammatory activity by controlling many inflammatory mediators (including histamine, IL-10 and various cytokines) and contributing to pain relief [1,10, 11]
  • Antioxidant activity – chinensis was shown to contain the highest antioxidant concentration amongst 112 screened Chinese medicinal plants [1,12]
  • Antidiarrheal and hepatoprotective properties; G, chinensis inhibited the binding of coli-produced toxins onto intestinal cells [1,13]

Chemically, G. chinensis is rich in gallotannin, the primary bioactive ones being pentagalloylglucose, 3-galloyl-gallic acid and 4-gaolloyl-gallic acid which are believed to drive many of it’s health benefits [1].

We have included Galla chinensis in our V-Defence 2 Formula due to its documented effects for supporting our anti-viral mechanisms.* 


Artemisia annua

Known as sweet wormwood, Artemisia annua is an herb native to China but at present grows wild throughout Asia, North America and Europe [14]. A. annua has featured in Chinese pharmacopeia for over two millennia under the name of Quing Hao. The earliest records of its use date from 168BC and suggest it was used as a remedy for hemorrhoids. Newer scriptures note its uses as an anti-inflammatory, anti-febrile and anti-malarial agent [14].

The main bioactive compound of A. annua is artemisinin, one of the most potent anti-malarial compounds known and observed to clear fever twice as rapid (and reduce parasite biomass 1,000 times more effiecient) as other anti-malarials. Artemisin has been chemically synthesized to be used in commercial anti-malarial drugs [14,15].

In addition to its anti-malarial activity, A. annua has been observed to possess qualities such as:

  • Anti-viral action against herpes viruses (e.g. Epstein-Barr, HMCV, HSV-1), hepatitis B & C and certain strains of SARS-associated coronaviruses [16,17]
  • Anti-parasitic activity against protozoans such as Trypanosoma, Toxoplasma gondii & multiple Schistosoma strains [16]
  • Anti-fungal activity against Cryptococcus neoformans and Aspergillus fumigatus [16]
  • Anti-inflammatory and anti-allergic activity, in particular against septic inflammation [16,18]
  • Anti-cancer activity against certain breast, central nervous system, colon, leukemia, melanoma, ovarian and renal cancer cells [16,19,20]

We have included Artemisia annua in our V-Defence 2 Formula to synergistically support your immune system with Galla chinensis.*


Zingiber officinale

Ginger (Zingiber siccatum, Gan Jiang; heat-processed extract of Zingiber officinale) is a powerful plant remedy used for centuries in TCM for the treatment of (among others):

  • Infections
  • Gastrointestinal disorders
  • Food poisoning
  • Dizziness
  • Diarrhea
  • Furthermore, ginger is rich in two important phytochemicals: gingerol and Shogaol [21].

Clinical trials have demonstrated that ginger can have powerful antibacterial properties, for example in inhibiting the proliferation of MRSa (Methycyllin-Resistant Staphylococus aureus) through the inhibition of the SaHPPIC (Staphylococcus aureus 6Hydroxymethyl-7-8 dihydropterin) enzyme [22]. This enzyme is essential for the docking of bacteria on cells’ memberane’s and thus their further proliferation.

The presence of ginger not only enhances V-Defence 2 Formula’s anti-bacterial support but also mitigates its potential impact on the gastrointestinal system.*
