The Importance of Tea
Benefits for Humans & Other Animals

 

Karen Shaw Becker, DVM, NMD

 

Types of teas

n    Green

n    Black

n    White

n    Herbal

 

Tea plant: Camellia sinensis

 

n    Small, evergreen shrub

n    Habitat: primarily grown in Japan, China

n    The harvested leaves produce green, black, oolong and white teas

n    Variance in flavors due to processing

 

What’s the difference?

n    Green: young leaves picked and dried quickly, minimally oxidized then fired

n    Black: complete oxidation of the mature leaf prior to firing

n    Oolong: leaves are rolled after harvesting, allowing the volatile oils to react with air. Very slow oxidation prior to firing

n    White: picked before the leaf buds have opened (buds are covered with short, white hairs), leaves are steamed and dried quickly

 

Green Tea Health Benefits:

 

n     Polyphenols (potent antioxidants):

n     scavenge free radicals (20-30 times the potency of vitamin E)

n    Vitamin C: strengthens immune system

n    Lowers LDL cholesterol

n    Increases HDL cholesterol

n    Reduces blood pressure

n    Nutrients: carotene, B1, B2, B6. Folic Acid, Manganese, potassium

 

Other benefits

n      American Journal of Clinical Nutrition found green tea significantly increased energy expenditure and fat oxidation

 

n      American Association for Cancer Research found green tea has the ability to prevent gene damage (associated with the onset of cancer)

 

n      Contains epigallocatechin-3-gallate (EGCG) which slows angiogenesis (tumor blood vessel growth)

 

n      Clinical studies confirm green tea’s role in reducing heart disease, incidence of stroke

 

Black Tea Health Benefits:

 

n    Antioxidants keep blood vessels supple, promote healthy blood flow

n    Flavonoids reduce incidence of atherosclerosis (narrowing of arteries)

n    Tannins: Chelate heavy metals, mainly lead and iron (used at Berlin Zoo with rhinos, Ramphastids, mynahs and tanagers for iron flushing)

 

White Tea Health Benefits:

 

n    Strongly inhibits mutagenicity (a result of unrepaired DNA damage), potent anti-cancer properties

n    Abundant polyphenols (antioxidants)

n    Aids the body in metabolizing carcinogens

 

Caffeine

n    Green, black, oolong and white teas must be decaffeinated for birds

n    Purchase teas that are decaffeinated by water and carbon dioxide (to retain the polyphenols) NOT ethyl acetate

n    Herbal teas are naturally caffeine-free

 

Herbal Teas:

n     Chamomile:

n    Significant increases in urinary hippurate (a breakdown product of polyphenols) which has antibiotic properties

n    Increases in urinary glycine, an amino acid that has been shown to relieve muscle spasms

n    Contains nerve relaxants (acts like a natural calmative/sedative)

n    Beneficial for insomnia (and nightmares), pain, stress, hyperactivity, anxiety

n    Digestive tonic, IBD

Herbal Teas:

n     Rose hips

n    Natural source of vitamin C and bioflavonoids. Potent blood, liver and kidney tonic. Use for fatigue, recovery from illness

n     Peppermint

n    G.I. upset, antiseptic properties, anti-viral

n     Ginger root

n    Improves circulation,  anti-nausea, good for arthritis

n     Anise seed (parsley family)

n    Aids digestion, soothes cough, bronchitis

 

Herbal teas:

 

n     St. John’s Wort

n    Mental calmness, anti-anxiety, anti-OCD

n     Raspberry

n    Rich in calcium, magnesium

n    Considered a “female” tonic (used at Berlin Zoo for pregnant Babirusa and other animals to aid in uterine contraction)

n     Echinacea

n    Immune stimulation (interferon and T cell activity)

 

 

Herbal Teas:

n     Essiac

n    Founded in 1922 by Canadian nurse Rene Caisse

n    Several herbs, including burdock root, sheep sorrel, slippery elm, Indian rhubarb

n    Used to restore health to thousands of individuals (cancer)

n    Herbs are used to help cleanse the blood, nourish the immune system

 

Herbal teas:

n     Rooibos (“Red” tea)

n    Grown high in the mountains of South Africa

n    Mineral rich (low tannins)

n    Contains natural anti-spasmodics (helps with colic, indigestion, muscle fatigue)

n    Rich in flavonoids, especially aspalathin, which is anti-allergenic, anti-inflammatory

n    Contains alpha-hydroxy acid, antioxidants and SOD

n    Potent anti-mutagenic components that inhibits chromosomal breakdown

n    Abundant oligosaccharides that are anti-viral

 

 

 

Brewing hints:

n    Use hot, not boiling water to make tea

n    Let the tea cool completely before offering it to your birds

n    Remove the tea bag before serving

n    If your bird is suspicious, steep tea for a shorter period (make tea more dilute)

n    Substitute tea for water when making soft foods, pasta, rice, etc.

n    Never replace water with tea!  Suggests a fresh water source daily.
