A
media release by MNT titled “Herbs that can boost your mood and memory”,
explains significant benefits as per a new research from Northumbria University’s Department of Psychology which has undertaken a number
of studies into the effects of herbs and substances on mood and memory. Researchers
found beneficial properties in tea (chamomile and peppermint) and aromas (rosemary
and lavender).
The
findings indicated that while chamomile had a calming and sedative effect, peppermint
enhanced and aroused both mood and cognition. Another research on 150 healthy
persons revealed that rosemary scented place significantly enhanced prospective
memory, while lavender scented place reflected significantly increased calmness
and contentedness.
Tea
leaves have been used to improve the health as well as appearance of skin and
hair. Several studies have highlighted their anti-aging and health-promoting
effects, showing antioxidant, anti-aging, anti-inflammatory, and anti-cancer
benefits of tea. When combined with other ingredients in beauty formulations,
tea extract helps to enhance their effects, a synergy that helps improve skin’s
appearance, texture, and function. Frequent exfoliation allows active tea
constituents to better penetrate the skin with most beneficial exfoliating
agents alpha-hydroxy.
Carotenoids
in tea are potent fat-soluble antioxidants that help quench free radicals
generated by ultraviolet rays. Tea also contains 25-30% flavonoids, which
include water-soluble plant pigments known as polyphenols. The major polyphenol
in tea is epigallocatechin-3 gallate, or EGCG. Oral and topical use of tea and
EGCG helps to inhibit inflammation and oxidative stress, and may help to
prevent photoaging and cancers of the skin. The combination of these natural
antioxidants improves skin health, giving it a smoother, brighter and healthier look.
Tea
is also a potent inducer of superoxide dismutase (SOD), an enzyme that quenches
excess superoxide radicals and other reactive oxygen species. Among elderly
persons, the amount of SOD in normal skin diminishes and is incapable of
adequately neutralizing large amounts of reactive oxygen species. Because of environmental
and other pollutants (sunlight, smoking diet) contributing to the generation of
reactive oxygen species, it is most critical to optimize SOD levels through the
use of tea and other flavonoids.
In
combination with topical tea, natural fruit acids called alpha-hydroxy acids
rejuvenate the skin by encouraging the shedding of old, sun-damaged cells on
the skin’s surface.32-35 Alpha-hydroxy acids loosen the glue-like substances
that bind skin surface cells to each other, allowing the dead skin to peel off
and the skin underneath to emerge. This underlying skin has a fresher,
healthier look, with a more even color and texture. Exfoliation with
alpha-hydroxy acids allows topical antioxidant agents, such as tea, to affect
the newly exposed cells to greatest benefit.
The
extracts of tea buds and leaves are very effective ingredient in natural
organic beauty products. Green teas have the highest concentration of
antioxidant properties (polyphenol and flavonoid) and have anti-carcinogenic
and anti-mutagenic properties which provide excellent skin nourishment.
HerballyRadiant’s natural formulations extensively use tea extracts (white & green
tea) as well as lavender and rosemary essential oils to enhance their overall
effect.
