Herbal teas are an amazing way to leverage improvements across the board so here's ~20 of my favourites to try with their main benefits listed below: - Astragalus (saponins/polysaccharides upregulate Nrf2/antioxidant enzyme pathways, reduce inflammation such as IL-6, restores the intestinal barrier, increases goblet cell number and gut mucosal layer thickness, potentially benefits fatigue and loose stools/poor appetite, used adjunctively in China alongside conventional hepatitis therapy (not medical advice, benefits insulin sensitivity and glycemic control due to effects on the gut barrier, increased interferon activity, NK cell function, reduced frequency/duration of upper respiratory infections) - Ginger (accelerates gastric emptying and increased antral contractions - great for gut motility, reduces post meal postprandial fullness, pregnancy-related nausea, chemotherapy-induced nausea, and post-operative nausea all show benefit, Gingerols/shogaols inhibit COX-2 and 5-LOX (similar pathway to NSAIDs), reducing prostaglandin/leukotriene-driven inflammation, reduces neutrophil chemotaxis to the gut reducing gut damage in cases of high inflammation, muscle soreness and menstrual pain, reductions in fasting glucose and HbA1c, increases LH which benefits testosterone production) - Chinese skullcap (benefits anxiety via Baicalein and wogonin binding the benzodiazepine site of the GABA-A receptor to stimulate relaxedness, baicalin/baicalein show hepatoprotective effects, inhibits NF-κB signalling, reduces pro-inflammatory cytokines in models of colitis and arthritis, Traditionally used in TCM formulas for GI upset, diarrhea with heat signs, benefits the intestinal barrier and leaky gut) - Green sencha (lowers oxidative stress and inflammatory markers, shifts microbiota toward higher Bacteroidetes/lower Firmicutes ratio, increase short-chain fatty acid (SCFA)-producing bacteria and feeds akkermansia and bifidobacteria, lowers fasting glucose and insulin sensitivity, L theanine in green tea helps stabilise mast cells, lowers inflammation, benefits tight junction proteins, promotes calmness and the 'zen' focus due to increasing alpha brain waves) - Lemon balm (inhibits GABA transaminase - the enzyme that breaks down GABA, reduced anxiety/stress ratings and improved mood and cognitive performance under stress after acute dosing, used for centuries for bloating, gas, and functional dyspepsia, anti-inflammatory and antiviral properties) - Chamomile (Apigenin - the major flavnoid in chamomile - binds the benzodiazepine site of the GABA-A receptor to induce relaxation, reduces anxiety symptoms, improved subjective sleep quality with chamomile tea/extract, COX-2 and cytokine pathway inhibition, antioxidant activity from flavonoids (apigenin, luteolin, quercetin)) - Chinese golden thread (AMPK activation from berberine within the herb, berberine has benefits on mucus production, akkermansia mucinophilla, reshaping the microbiome suppressing pathogenic microbes, traditionally used for diarrhea, dysentery, and GI infections in Traditional Chinese Medicine, inhibits NF-κB and other inflammatory cytokines) - Peppermint (relaxes GI smooth muscle via calcium-channel blockade, significant improvement in IBS global symptoms, abdominal pain, and bloating making it great for IBS, nausea relief, can cause reflux in susceptible individuals due to relaxing the LES - Lower Oesophageal Spinchter) - Roobious (significantly raises plasma total antioxidant capacity, containing aspalathin, a flavonoid essentially not found in any other plant, lowers glucose in rodent models, significant reductions in LDL cholesterol, increases in HDL, and reduced markers of oxidative lipid damage in humans, weak estrogenic activity, naturally caffeine-free and low in tannins) - Turmeric (curcumin inhibits NF-κB, COX-2, and multiple inflammatory cytokines across many human studies, (increases beneficial genera, reducing pro-inflammatory taxa) and supports gut barrier integrity, stimulates bile flow, reduced dyspepsia symptoms, potent free-radical scavenger and Nrf2 activator, increases BDNF making it potentially beneficial for low mood) - Nettle (inhibits inflammatory cytokines (TNF-α, IL-1β) and COX/LOX pathways, antioxidant flavonoid/phenolic content, stabilises mast cells) - Rose hip (rose hip powder reduces pain and inflammatory markers (CRP) in osteoarthritis and rheumatoid arthritis, extremely high vitamin C and carotenoid content, antioxidant activity, Human studies show modest improvements in fasting glucose, LDL cholesterol, and some reduction in abdominal fat with regular rose hip powder/tea intake over several weeks) - Hibiscus (multiple human RCTs and meta-analyses consistently show hibiscus tea (roughly 2–3 cups/day) modestly but reliably lowers both systolic and diastolic blood pressure, comparable in some trials to low-dose antihypertensive medication - not medical advice, reductions in fasting glucose, total cholesterol, and LDL with regular intake, Rich in anthocyanins, Traditionally used as a mild laxative and for digestive complaints in various cultures) - Holy basil (Tulsi) (Small studies in adults with self-reported stress show reduced perceived stress, anxiety, and depression scores, Multiple human RCTs in type 2 diabetics show meaningful reductions in fasting and post-prandial glucose with tulsi leaf extract/tea, Eugenol and ursolic acid (key constituents) show COX-2 inhibition and reduced inflammatory cytokines, Strong antioxidant activity, immunomodulatory effects (enhanced NK cell activity, antimicrobial action against several respiratory pathogens) - Fennel (antispasmodic activity on GI smooth muscle, antibiofilm effects, mildly antimicrobial, also has some antioxidant effects) - Cinammon (cassia cinnamon, 1–6 g/day) show modest but fairly consistent reductions in fasting glucose in type 2 diabetics so great for blood sugar and insulin, Cinnamaldehyde and procyanidins show good antioxidant and anti-inflammatory activity, protects the gut barrier) - Yerba mate (anti-inflammatory activity from polyphenol content, contains caffeine + chlorogenic acid contents, improves lipid profiles (reduced LDL, increased HDL), improves glucose tolerance and insulin sensitivity, mate polyphenols favourably shift gut microbiota composition and reduce markers of metabolic endotoxemia) - Pu-erh (suppresses bile-salt-hydrolase-producing gut bacteria, which alters bile acid signaling (inhibiting intestinal FXR-FGF15/19 signaling while activating hepatic FXR-SHP signaling) to increase hepatic bile acid production and fecal cholesterol excretion, human studies show reductions in total cholesterol, LDL, and triglycerides) - Cacao (makes dopamine and neurotransmitter last longer in the brain, strengthens the gut barrier, feeds beneficial bacteria such as bifidobacteria, highly potent antioxidant much more than blueberries)
