Pharmacognosy intro
Elettaria cardamomum (L.) Maton, Zingiberaceae. Seeds contained within fruit pods. Common names include green cardamom, true cardamom, and "Queen of Spices." Tridoshic in Ayurvedic classification, balancing all three doshas. The essential oil contains two dominant compounds: 1,8-cineole (eucalyptol, 20-60%) and alpha-terpinyl acetate (20-55%). Secondary compounds include linalool, limonene, beta-pinene, and geraniol. Polyphenolic constituents include quercetin, kaempferol, luteolin, pelargonidin, gallic acid, and caffeic acid. Antioxidant capacity is superior to synthetic BHT, with ORAC values of 3100 umol TE/g versus 2500 umol TE/g for BHT. 1,8-Cineole and alpha-terpinyl acetate drive 40-60% suppression of TNF-alpha and IL-6 in murine macrophages (IC50: 18 ug/mL) by directly binding inflammatory cytokines and downregulating the NF-kappaB transcription factor pathway through phenolic-flavonoid compounds. 1,8-Cineole has documented anti-inflammatory effects on airways by inhibiting cytokines along the arachidonic acid pathway, with human asthma studies using 200 mg/day capsules reducing the need for corticosteroid therapy. Alpha-terpinyl acetate showed mixed-type acetylcholinesterase inhibition (IC50: 61.87 ug/mL) and potent anti-amyloid-beta fibrillization activity exceeding 50%. Cardamom also inhibits alpha-amylase (IC50: 220.5 ug/mL) and pancreatic lipase (IC50: 288.75 ug/mL). Human clinical evidence spans multiple domains. A double-blind RCT with 83 T2DM patients found 3g/day green cardamom for 10 weeks significantly decreased HbA1c (-0.4%), insulin (-2.8 uIU/dL), HOMA-IR (-1.7), and triglycerides (-39.9 mg/dL) via increased SIRT1 concentration (+2.3 ng/mL) (Aghasi et al., 2019). An RCT with 80 pre-diabetic women found 3g/day for 8 weeks significantly decreased hs-CRP (p=0.02), hs-CRP:IL-6 ratio (p=0.008), and MDA (p=0.009) versus placebo (Kazemi et al., 2017). A meta-analysis of 8 RCTs (595 patients) confirmed cardamom significantly reduced diastolic blood pressure (WMD: -0.91 mmHg), hs-CRP (SMD: -0.60), IL-6 (WMD: -1.25), and TNF-alpha (WMD: -2.10) (Heydarian et al., 2023). Daily 3g supplementation reduced dyspepsia symptoms by 50% versus placebo (p<0.01). Preclinical data shows cardamom (500 mg/kg/day, 4 weeks) reversed cafeteria diet-induced neuroinflammation in mice, reducing hippocampal TNF-alpha (p<0.01), improving recognition memory (p<0.01), and reducing anxiety-like marble burying behavior (p<0.001) (AL-Dalaeen et al., 2026).
