Mechanism

Holy Basil (Ocimum tenuiflorum) contains eugenol, rosmarinic acid, ursolic acid, and ocimumosides. Eugenol inhibits COX-2 and 5-LOX, providing anti-inflammatory effects. Ursolic acid activates AMPK and inhibits NF-kB. Ocimumosides (A and B) exhibit anti-stress activity by normalizing corticotropin-releasing hormone (CRH) and cortisol levels. Holy Basil also inhibits cortisol synthesis at the adrenal level, modulates GABAergic and serotonergic neurotransmission, has adaptogenic effects via normalization of hypothalamic-pituitary-adrenal axis, and exhibits hypoglycemic action via enhanced insulin secretion and peripheral glucose uptake.

Standard Dosing

500-1000mg daily (standardized extract) or 300mg of high-potency extract

Timing

Morning and/or evening with meals. Tulsi tea form is also traditional.

Cycle Duration

Cycle 8-12 weeks on, 2-4 weeks off, or ongoing at lower doses

Side Effects

  • Mild nausea
  • GI discomfort
  • Potential anti-fertility effects (animal data — reduced sperm count)
  • Hypoglycemia in diabetic patients

Contraindications

  • Pregnancy (traditional emmenagogue use — may stimulate uterine contractions)
  • Planned surgery (antiplatelet effects)
  • Hypothyroidism (may reduce T4 levels in some studies)

Mechanism

Reishi contains triterpenoids (ganoderic acids, >130 identified) and polysaccharides (beta-glucans). Ganoderic acids inhibit histamine release, 5-alpha-reductase (DHT reduction), and ACE (angiotensin-converting enzyme). Beta-glucans (1,3/1,6-D-glucan) activate innate immunity via Dectin-1, CR3, and TLR-2 receptors on macrophages, dendritic cells, and NK cells. Reishi modulates the adaptive immune system by promoting Th1/Th2 balance and enhancing regulatory T-cell function. It also supports GABAergic signaling (calming effect), inhibits NF-kB, and modulates gut microbiome composition. Triterpenes support liver function via Phase I/II enzyme modulation.

Standard Dosing

1000-3000mg daily (dual extract: hot water + alcohol for both polysaccharides and triterpenes)

Timing

Evening preferred (calming, supports sleep). With meals.

Cycle Duration

ongoing or cycle 12 weeks on, 4 weeks off

Side Effects

  • GI upset
  • Dry mouth/throat
  • Dizziness
  • Nosebleeds (antiplatelet effect)
  • Rare: hepatotoxicity (powdered whole mushroom products)
  • Skin rash

Contraindications

  • Autoimmune conditions (active flare — immunomodulatory)
  • Bleeding disorders
  • Pre-surgery (discontinue 2 weeks prior)
  • Organ transplant recipients on immunosuppressants
