A bit about green tea.
VMV HYPOALLERGENICS® uses green tea in several of its products due to green tea’s robust medical literature: there are several articles that are evidence based on green tea, its polyphenols and epigaloocatechins AND (crucial for VMV) its virtual non-allergenicity. Medical validity, particularly with the quantity of studies that green tea has, plus hypoallergenicity, are the primary reasons VMV uses green tea for its antioxidant, antimicrobial, and skin rejuvenating effects in so many of its products.
White tea is getting a lot of attention but our research into the medical literature has so far shown only anecdotal data and no evidence-based articles. This is in contrast to green tea’s multiple scientific and evidence-based laboratory/phase I to IV studies.
“My CAMP* list doesn’t include some of your products because green tea, which you use a lot, is defaulted as a ‘botanical’ by CAMP. But I’ve had no problems with any of your products, even those with green tea. Why?”
For the sake of categorization, green tea is sometimes classified under “botanicals” and CAMP lists all botanicals as optional cross-reactors to fragrance. In CAMP (and CARD), this includes green tea by default despite its having no reports of cross reaction with fragrance. What many doctors do is manually remove green tea from the list.
VMV has been using green tea for almost a decade. There have been 0 instances of contact dermatitis even among a large number of patients with a positive patch test result to balsam of peru, colophony, fragrance I, cinnamates, fragrance II and the new individual fragrance allergens in the NACDG and ESSCA1 allergen lists (and green tea is not included as an allergen in these lists).
We have also done numerous photopatch tests using these allergens and the leading series of 13 plant and 24 fragrance allergens. On the patients with positive reactions (photopath and patch), none have reacted to green tea and so far, no literature reports green tea reactions.
