STUDIES ON VARIOUS INGREDIENTS PRESENT IN SIPPING BEAUTY TEA
Green Tea
Skin: Irradiated green tea polyphenol can be used as a natural ingredient with excellent physiological functions for the human skin through cosmetic or food composition.

Weight Loss: Consumption of green tea may enhance health because it reduces the incidence of cancer in various experimental models, is a potent antioxidant, and modulates serum cholesterol concentrations. Green tea also has effects on body weight and energy expenditure.

Efficacy of a green tea extract rich in catechin polyphenols and caffeine in increasing 24-h energy expenditure and fat oxidation in humans.

Red Tea
Antioxidants: Recent studies have shown that Red Tea Tea possesses significant antioxidant and free radical scavenging properties due to substances that mimic the activity of super oxide dimutase SOD. The antioxidant and free radical scavenging activity of Red Tea has been compared with green, black and Oolong teas18. With a DPPH (diphenyl-_-picrylhydrazyl) radical scavenging method, both fermented and unfermented Red Tea’s extracts were found to be stronger free radical inhibitors than either black or Oolong tea but slightly less than green tea on a mass equivalent basis.

UV and Dermal: Long term cocoa ingestion leads to an increased resistance against UV-induced erythema and a lowered transepidermal water loss. Subsequent to the intake of high flavanol cocoa, dermal blood flow was significantly increased by 1.7-fold at t = 2 h and oxygen saturation was elevated 1.8-fold. No statistically significant changes were found upon intake of low flavanol cocoa. Flavanol-rich cocoa consumption acutely increases dermal blood flow and oxygen saturation.

Bromelain
This substance has shown distinct pharmacological promise. Its properties include: (1) interference with growth of malignant cells; (2) inhibition of platelet aggregation; (3) fibrinolytic activity; (4) anti-inflammatory action; (5) skin debridement properties. These biological functions of bromelain, a non-toxic compound, have therapeutic values in modulating: (a) tumor growth; (b) blood coagulation; (c) inflammatory changes; (d) debridement of third degree burns; (e) enhancement of absorption of drugs. The mechanism of action of bromelain affecting these varied biological effects relates in part to its modulation of the arachidonate cascade.

Chlorophyll
Internal Deodorant: Chlorophyll is the most widely distributed natural plant green pigment, and chlorophyllin (CHL) is the sodium-copper salts of chlorophyll derivatives with their phytyl alcohol removed (Fig. 1). CHL has been marketed as an internal deodorant for controlling body odor and as an accelerant in wound healing.

Blood
Skin: Seeds from five varieties of Tunisian Citrus fruits, namely blood orange (Citrus sinensis), sweet orange (Citrus sinensis), lemon (Citrus limon L.), bergamot (Citrus bergamia) and bitter orange (Citrus aurantium), were examined for their composition of lipid classes and fatty acids. In addition, the oil yield, total fatty acids, palmitic, oleic and linoleic acids were determined. The Citrus seed oils had three lipid classes as determined by thin-layer chromatography. Triacylglycerols were the major oil class in all varieties. Gas chromatographic analyses revealed that the main fatty acids were palmitic, oleic and linoleic acids.

Rosehip
Skin:The physicochemical properties of oil from Rosa affinis rubiginosa seeds were analyzed after extraction by (i) organic solvent, (ii) cold pressing, and (iii) cold pressing assisted by enzymatic pretreatment using a mixture of the Novo-Nordisk A/S products Cellubrix (cellulase and hemicellulase activities) and Olivex (pectinase, cellulase, and hemicellulase activities). This result is quite important for cosmetic oil because all-trans-retinoic acid is the main bioactive component responsible for the regenerative properties of this oil.

Hibiscus Flowers
Hibiscus contains a high organic acids percentage (15-30%), oxalic acid, tartaric acid, malic acid, succininc acid and hibiscic acid among them. Oxalic and tartaric acids constitute more than three quarters of the total acids present in Hibiscus. Hibiscus and its derived extracts have an important inhibitory activity on the growth of fungus and yeasts. Additionally, they have a remarkable inhibitory activity on enzymes such as the acid phosphatase, the alkaline phosphatase, the glutamate-oxalacetate transaminase and the glutamate-pyruvate transaminase. The antioxidant properties of Hibiscus were assessed by comparing its activity with those of BHA and β-carotene. The results showed that the Hibiscus extract had stronger antioxidant activity than BHA and β-carotene. In that study, the generation of conjugated diene compounds and of malonic dialdehyde were evaluated by using the thiobarbituric acid method. The results showed that 200 ppm of a methanol extract of Hibiscus were able to inhibit more than 85% of diene-conjugated compounds generation after 7 days incubation at 40 C. This activity was closely related to the extract’s contents of phenolic compounds, mainly the anthocyans.

Vitamin C
Vitamin C contributes to human health in many important ways, including promoting the health and beauty of the skin. Vitamin C decreases production of the pigment melanin, allowing for lighter and brighter skin. It is required for collagen synthesis, which may contribute to fewer wrinkles, and also helps facilitate skin repair after an injury. Vitamin E is a strong antioxidant that is able to suppress free radicals in the skin. Its ability to be regenerated in the skin is enhanced by vitamin C.

Chamomile
In one study, chamomile attached to receptors in the body that are also the targets of prescription sedative medications. Low doses produced a calming effect, while higher doses were more likely to cause sleep. Flumazenil, a benzodiazepine receptor antagonist, at a dose of 3 mg/kg showed a significant antagonistic effect on the shortening in sleep latency induced by chamomile extract.
