    Scientific name: Lycium barbarum

    Bioactive components: Carotenoids, riboflavin, thiamine, nicotinic acid, polysaccharides

    Benefits: Red goji berries have been associated with numerous benefits including anti-aging, antioxidative, anti-fatigue, anticancer, anti-diabetic, anti-viral, hepatoprotective, cardioprotective, neuroprotective, hypolipidemic, anti-osteoporosis, anti-inflammatory, and immunomodulating effects.1,2,3 They have been show to significantly reduce blood glucose and serum total cholesterol, as well as reduce fatigue and stress.4,5,6 Their polysaccharides have neuroprotective effects that can reduce the risk of Alzheimer's disease.7,8

    Scientific name: Lycium ruthenicum

    Bioactive components: Anthocyanins, phenolic compounds and tannins

    Benefits: Black goji berry had the highest phenolic, condensed tannin content and monomeric anthocyanin content among goji berries, with more than twice the antioxidant capacities of red goji berries.9,10 Aside from its strong antioxidant and anti-inflammatory effects, it has been shown to improve gut health.11,12,13 Black goji berries also have neuroprotective effects that can ameliorate Alzheimer's disease.14,15,16

    Scientific name: Zingiber officinale

    Bioactive components: Antioxidative, phenolic compounds (gingerols, shogaols, and paradols), terpenes (β-bisabolene, α-curcumene, zingiberene, α-farnesene, and β-sesquiphellandrene)

    Benefits: Ginger has been associated with numerous biological activities including antioxidant, anti-inflammatory, antimicrobial, anticancer, neuroprotective, cardiovascular protective, respiratory protective, antiobesity, antidiabetic, antinausea, and antiemetic activities.17 It has neuroprotective and anti-neuroinflammatory effects as well.18,19 Clinical studies have shown int can significantly reduce nausea (including pregnancy-related nausea)20,21, and can also significantly reduce body weight in overweight or obese individuals.22 Ginger can also aid indigestion by speeding up gastric emptying.23

    Scientific name: Citrus reticulata peel

    Bioactive components: Phenolic compounds (caffeic, p-coumaric, ferulic and sinapic acid), flavonones (naringin and hesperidin)

    Benefits: Orange peel has high anti-oxidant activity that can reduce risk of chronic disease.24,25 It also has nobiletin which confers neuroprotective effects, reducing the risk of neurogenerative diseases such as Alzheimer's and Parkinson's disease.26

    Scientific name: Chrysanthemum morifolium

    Bioactive components: Flavonoids (naringenin and apigenin), phenolic compounds, rare arylnaphthalene-type lignans

    Benefits: Chrysanthemum has strong anti-oxidant and anti-inflammatory effects.27 It is also rich in flavonoids that can decrease blood glucose and reduced total fat and cholesterol,28 as well as confer anti-depressive effects through metabolic pathways.29 Its rare arylnaphthalene-type lignans and phenolic glycosides also provide neuroprotective effects.30

    Scientific name: Mentha haplocalyx

    Bioactive components: Phenolic acids (e.g. rosmarinic and caffeic acids), flavones (e.g. luteolin derivatives), flavanones (e.g. eriocitrin derivatives) and polysaccharides (e.g. galactans)

    Benefits: Chinese peppermint (薄荷) has strong anti-oxidant as well as potential anti-aging effects.31,32

    Scientific name: Rosa rugosa

    Bioactive components: Phenolic acids, flavonoids, carotenoids, and polysaccharides

    Benefits: Chinese rose has strong anti-oxidant effects,33,34,35 The flavonoids from Chinese rose provide cardioprotective effects, while polysaccharides contribute to its anti-aging activity.36,37

    Scientific name: Hibiscus sabdariffa

    Bioactive components: Anthocyanins, polyphenols ( e.g. protocatechuic acid)

    Benefits: Roselle has demonstrated anti-obesity effects in both animal and human studies, by reducing fat accumulation and body fat.38,39,40,41 It also has prebiotic effects that modulates the gut microbiome.42

    Scientific name: Clitoria ternatea

    Bioactive components: Phenolic compounds, flavonoids (flavonol glycosides) and polyacylated anthocyanins

    Benefits: The blue pea flower has antioxidant, antihemolytic and antihypertensive effects - it has been shown to significantly improve antioxidant capacity, protect against oxidative stress and also reduce cholesterol levels.43,44,45 In addition, the flower has anti-inflammatory effects, which helps boost immunity.46

    Scientific name: Panax quinquefolium

    Bioactive components: Ginsenosides, ginseng proteins, polysaccharides (e.g. poly-furanosyl-pyranosyl-saccharides)

    Benefits: Ginsenosides from ginseng helps in vasorelaxation, antioxidative, anti-inflammatory, anti-cancer functions and has also been shown to lower blood sugar levels.47 Ginseng has been widely used in Traditional Chinese Medicine and scientific studies have also shown that American ginseng helps reduce body heat and lowers the body temperature.48 American ginseng, not only contains proteins that combat fatigue but its ginsenosides also help to boost immunity.49,50,51,52 Notably, American ginseng contains poly-furanosyl-pyranosyl-saccharides which have been shown to reduce the rate, severity and symptoms of upper respiratory tract infections such as from the common cold.53 American ginseng has also been shown to provide neuroprotective effects and boost cognitive function, reducing the risk of neurodegenerative diseases such as Alzheimer's and Parkinson's disease.54 Research has shown that American ginseng has significantly higher anti-oxidant activity than Asian ginseng.55

    Scientific name: Cymbopogon citratus

    Bioactive components: Terpenes (e.g. citral), terpenoids (e.g. geraniol), flavonoids (e.g. caffeic and chlorogenic acid)

    Benefits: Lemongrass is widely used in wellness products such as teas, essential oils and herbs as it has compounds with strong anti-oxidant activity.56,57 In particular, citral and geraniol from lemongrass has been shown to lower blood pressure and cholesterol levels.58,59
