Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
The principal stimulant alkaloid, driving alertness and much of coffee's pharmacological activity.
Major antioxidant polyphenols of the green and roasted bean, linked to metabolic and hypoglycaemic effects.
Present in unfiltered coffee (e.g. French press, espresso); raise LDL cholesterol, unlike paper-filtered coffee where they are largely removed.
Antioxidant flavonoids of the leaf, standardised in clinical extracts.
Unique diterpene and sesquiterpene lactones responsible for platelet-activating-factor antagonism and much of the neuroprotective and circulatory activity; also the basis of the bleeding-risk caution.
A neurotoxic compound present in the raw seed; the reason only cooked seed in small amounts, or standardised leaf extract, is used medicinally.

Safety, Cautions & Contraindications
Caffeine is the primary psychoactive component; excessive intake (>400 mg/day in adults, >200 mg/day in pregnancy) can cause anxiety, insomnia, palpitations, and elevated blood pressure. Caffeine dependence and withdrawal (headaches, fatigue) are well documented. Individuals with anxiety disorders, arrhythmias, or hypertension should limit intake. Cafestol and kahweol in unfiltered coffee (e.g., French press, espresso) raise LDL cholesterol; paper-filtered coffee removes these compounds. During pregnancy, limit to <200 mg caffeine/day due to risk of foetal growth restriction. Coffee may interact with certain medications including thyroid hormones, levothyroxine, and some antibiotics (ciprofloxacin increases caffeine levels). Heartburn and gastro-oesophageal reflux are common side effects in sensitive individuals (EFSA, 2015; NIH, 2023).
Duke (2002) notes clinical evidence (score 2) for coffee as an adsorbent (activated charcoal use), astringent, bronchodilator, and gastric stimulant. A key safety concern: unfiltered (e.g., French press or boiled) coffee raises LDL cholesterol (hypercholesterolemic effect, score 2) due to diterpenes cafestol and kahweol. Filtered coffee does not carry this risk. Duke notes coffee's CNS stimulant, diuretic, and hepatoprotective properties, though excessive consumption is associated with increased anxiety, tachycardia, and hypertension. It is contraindicated in peptic ulcer disease due to gastric acid stimulation (Duke, 2002).
Generally well tolerated at standard doses but notable interactions exist. Ginkgo has antiplatelet and anticoagulant effects and should not be combined with warfarin, aspirin, or other blood-thinning medications without medical supervision. May lower the seizure threshold — avoid in epilepsy. Possible side effects include headache, dizziness, and GI upset. The raw seeds contain ginkgotoxin and are toxic; only processed leaf extracts are used medicinally.
Duke (2002) rates ginkgo as + (downgraded from higher rating for safety concerns) while noting clinical evidence (score 2) for anti-aggregant (platelet-inhibitory), anti-Alzheimer, and antioxidant activities. Commission E approves ginkgo leaf extract for cognitive deficits, peripheral circulatory disorders, and vertigo. However, Duke emphasizes significant safety concerns: ginkgo substantially increases bleeding risk when combined with anticoagulants (warfarin, aspirin, NSAIDs) and may cause spontaneous bleeding at high doses alone. Dose: 120–240 mg standardized extract (EGb 761) daily. Contraindicated with anticoagulants without medical supervision (Duke, 2002).

Botanical Description
Evergreen shrub or small tree with glossy, dark green, oval leaves in opposite pairs. Small, fragrant, white, star-shaped flowers cluster along the branches, followed by clusters of green berries ('cherries') that ripen to red and each contain two flattened seeds - the coffee beans.[1]
Ancient deciduous tree, a 'living fossil' with no close living relatives, bearing distinctive fan-shaped leaves with parallel forking veins that turn brilliant gold in autumn. The tree is dioecious (separate male and female trees); female trees bear fleshy, foul-smelling seed coats surrounding an edible inner nut (ginkgo nut) once the outer flesh is removed.[2]
Habitat
Native to the highland forests of Ethiopia and South Sudan; cultivated across the tropical highland belt worldwide (Latin America, Africa, Asia) at elevation, on well-drained, often volcanic soils.
Native to China, where a small number of wild populations survive; now cultivated worldwide as a resilient, pollution-tolerant ornamental and medicinal tree.
Harvesting
Ripe red berries are hand- or machine-picked, then processed (washed or dried) to remove the fruit pulp and expose the two seeds ('beans'), which are dried, hulled and roasted before use.
Leaves are picked in late summer to autumn, when flavonoid and terpenoid content is highest, and processed into standardised extracts; the inner seed is collected in autumn from fallen fruit, with the malodorous outer flesh removed (handled with gloves, as it can irritate skin).
Traditional Uses
Coffee has a centuries-long tradition, originating in Ethiopia and spreading through the Arab world and beyond, as a stimulant beverage taken for alertness and to counter fatigue; its seed and leaf extracts have more recently been studied for antioxidant, metabolic and neuroprotective properties.[1]
Ginkgo leaf and seed have a long East Asian tradition: the seed used in traditional Chinese medicine (in small, cooked amounts) for respiratory complaints, and the leaf, though a more recent addition to Western herbalism, now one of the most extensively studied botanicals for cognitive and peripheral circulatory support, reflecting decades of standardised-extract clinical research.[2]
Preparations
Decaffeinated or standardised green/roasted bean or leaf extract, taken as capsules for antioxidant or metabolic support studies.
Dosage
The EFSA Scientific Opinion on the safety of caffeine concluded that habitual caffeine intakes up to about 400 mg daily (roughly 3-4 cups of brewed coffee) do not raise safety concerns for healthy adults, and that single doses up to 200 mg are likewise not of concern. For pregnant women EFSA sets a lower figure of up to 200 mg per day. Note this is a safe-intake ceiling for caffeine, not a therapeutic dose of coffee. Educational reference only, not a prescription.
Clinical trials for cognitive and circulatory support commonly use around 120-240 mg of standardised leaf extract daily, in divided doses. Educational reference only, not a prescription.
