Secondary = compound plant produces in response to environment to assist its survival - active in humans & central in herbal medicine!
4 primary metabolites in plants?
Starch = energy storage
Chlorophyll = carb production
Cellulose = withstand cellular pressure - shape
Lignin = structural support- skeleton
2 examples of secondary metabolites?
Coffee beans - caffeine (an alkaloid) is a natural pesticide & stimulates human NS
Tannins - protect woody part of plant from decomposition/insects - reduce watery mucous in humans eg green tea
What’s an infusion & when to use?
2tsp/cup x 3

1tsp/cup x 3
What’s a syrup & when to use
Decoction + sweetener (preserves)

What’s a TINCTURE & uses?
Extracts FAT soluble photochemicals
Steep in alcohol or vinegar (preserves)
Concentrated & fast acting
What are GLYCERITES & uses?
Stoped in glycerine (thick/sweet fat/oil)
If can’t consume alcohol - but reduced extraction & shelf life

SAPONINS - adaptogenic, steroid effect, liquorice
TANNINS- astringent, dries, green tea
TERPENES- antispasmodic GI & lungs & antimicrobial, lavender
What is CHOLERETIC & CHOLAGOGUE?
CHOLERETIC - increases bile, dandelion
CHOLAGOGUE - stimulates gallbladder to release stored bile, artichoke
What is a DIAPHORETIC?
(Note; respiratory)
Promotes sweating/fever eg cinnamon
