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

Maca (Lepidium meyenii) contains unique macamides and macaenes (fatty acid derivatives), glucosinolates, and alkaloids. Unlike most adaptogens, maca does not directly affect testosterone, estrogen, or cortisol levels in blood. Instead, it appears to work as a 'hormonal normalizer' by acting on the hypothalamic-pituitary axis, modulating GnRH pulsatility and improving receptor sensitivity. Macamides interact with the endocannabinoid system (FAAH inhibition) and may modulate GABA and opioid pathways. Maca improves sexual function and desire through mechanisms independent of direct hormone elevation — likely central nervous system pathways.

Standard Dosing

1500-3000mg gelatinized maca daily

Timing

Morning with breakfast. Can be added to smoothies.

Cycle Duration

Cycle 12 weeks on, 4 weeks off, or ongoing

Side Effects

  • GI upset/bloating (raw maca — gelatinized is much better tolerated)
  • Insomnia
  • Mood changes
  • Increased heart rate (rare)
  • Hormonal acne (rare)

Contraindications

  • Hormone-sensitive cancers (glucosinolate metabolites may have hormonal effects)
  • Severe hypothyroidism (goitrogenic potential)
