1. Ginger

( Zingiber officinale)

Key bio-compounds: gingerols, shogaols, zingerone.

Benefits:

• Promotes digestion, reduces nausea (including motion sickness and pregnancy-related) via gastrointestinal motility and blocking nausea receptors.
• Anti-inflammatory and antioxidant action: elevates antioxidant enzymes (SOD, catalase, glutathione peroxidase) and reduces oxidative markers in animal studies.
• May support blood-sugar regulation and heart health: early research shows ginger may help with insulin sensitivity, fasting glucose, cholesterol and triglycerides.

2. Avarampoo

(Flowers of Senna Auriculata)

Key bio-compounds: phenolics, flavonoids, terpenoids, glycosides such as 5-O-methylquercetin 7-O-glucoside.

Benefits:

• Demonstrates antioxidant and antimicrobial activity in leaf/flower extracts: e.g., strong phenolic & flavonoid contents, inhibition of bacteria.
• Exhibits anti-inflammatory effects: the flower extract showed significant reduction in induced oedema in rats, attributed to flavonol glycosides.

• Potential antidiabetic action: computational docking studies show certain compounds from S. auriculata bind to α-amylase (a carbohydrate-digesting enzyme), suggesting glucose regulation potential.

3. Gymnema Tea

(Leaves of Gymnema sylvestre)

Key bio-compounds: gymnemic acids (triterpenoid saponins), glycosides, steroids (like stigmasterol), oleic acid.

Benefits:

• Antidiabetic/hypoglycemic: Review articles indicate the leaves contain gymnemic acids and saponins which help reduce sugar cravings and support blood-sugar control.
• Antimicrobial and other bioactivities: Leaf/root extracts show antimicrobial activity; GC-MS found compounds like eicosane, oleic acid, stigmasterol, vitamin E.

📌 Important Disclaimers & Tips

“Research-supported” doesn’t mean “cure” — lifestyle factors (diet, exercise, sleep) remain fundamental.

These herbs show potential benefits, but tea form vs. high-dose extracts may differ in potency, delivery and safety.

If you or someone is pregnant, on medication (especially for diabetes, blood pressure, anticoagulants), or has a disease condition — consult a healthcare professional before using herbal teas for therapeutic purposes.

Quality of the herb (source, processing, dosage), form (tea, extract, powder) and consistency matter for results.
