Flashcards in First 2 weeks Deck (29):
Bitters designation based on what?
physiologic function and taste rather than on chemical structure
Physiologic response to bitters?
Taste receptors: TAS2R (T2Rs)
Increases saliva, stimulates gastrin and HCl secretion, increase in pancreatic enzymes, release of bile, stimulates peristalsis
stimulate GI incretin hormones and helps to regulate appetite
Where are bitter receptors located?
tongue, colon, lungs, blood vessels, kidney, CNS, small intestine
5-10 drops in an ounce of water, sipped slowly over 15 minutes before the meal
~anorexia/geriatric patients to stimulate appetite
~hypochlorhydria, dyspepsia, gas and bloating, parasites, food allergies, malabsorption syndromes, rheumatic or autoimmune conditions, acne rosacea by increasing digestive secretions
~type II diabetes and dysglycemia due to supportive influence on blood sugars
Condition counter-indicated to use bittters
acute hyperacidic gastritis
What are the medicinal actions of Gentiana lutea?
a bitter=gastric stimulant
What are the constituents of gentiana lutea?
What is the medicinal use of gentiana lutea?
most indicated in conditions of poor, sluggish digestion (bloating, fullness after eating, pain) impaired appetite, anemia (increases Fe absorption), and malabsorption
it is used in the treatment of SIBO too
Is also a strong producer of saliva and treats dry mouth
Contraindications for gentiana lutea?
pregnancy, excess hydrochloric acid production, weak constitutions with nervous system irritability (ulcer patient)
Constituents of Lactuca virosa?
Medicinal action of lactuca virosa?
Medicinal uses of lactuca virosa?
non-constipating calmative, fairly sedative
Constituents of mentha piperita?
volatile oil, rosmarinic acid
Mechanism of action of mentha piperita?
chemically triggers cold-sensitive receptors in the skin, causes muscle relaxation by a blockage of calcium influx into the myocyte
does not cause actual drop in temperature
Medicinal action of mentha piperita?
Medicinal uses of mentha piperita?
IBS (enteric coated peppermint oil shown to benefit people with IBS)
liver and gallbladder complaints
mentha spicata has been studied to recude androgens in PCOS as a tea

~inhibition of platelet aggregation through inhibition of thromboxane and reduced platelet lipid peroxide formation
~inhibits substance P
~can act on TRVP channels, transient receptor potential superfamily of ion channels acting in the neurologic system
Medical actions of zingiber officinalis?
carminative, anti-emetic, stimulant, anti inflammatory, diaphoretic
Medicinal use of zingiber officinalis?
~GI conditions: improves gi motility while exerting antispasmodic effect
~gynecological conditions: relieves intensity and duration of pain in primary dysmenorrhea, also shown to reduce menorrhagia
~Inflammatory conditions: rheumatoid and oseoarthritis, migraine headaches, low dose 5-LOX inhibition, high dose COX-2 inhibition
