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 characteristic bioactive compounds of the resin-bearing flowers, varying widely in ratio and concentration between cultivars; THC is psychoactive, CBD is not.
Aromatic terpenes contribute to the plant's characteristic scent and may modulate cannabinoid effects.
Hemp seed is rich in polyunsaturated fatty acids (including omega-3 and omega-6), giving the pressed seed oil its nutritional value; essentially free of psychoactive cannabinoids.
Pharmacological Actions
Bacopa monnieri (Brahmi) extract and its saponins (bacopaside II, bacopasaponins) inhibit proliferation and induce apoptosis in colon and lung cancer cells (preclinical).
Traditional & Indicated Uses
inferred from anti-inflammatory action
Bacopaside II from Bacopa monnieri inhibits colon cancer cell growth via cell-cycle arrest and apoptosis (aquaporin-1 blockade), and its bacopasaponins are cytotoxic to lung (PC9) and colon (SW620) cancer cells (preclinical).

Safety, Cautions & Contraindications
Generally well tolerated at standard doses. The most commonly reported side effects are gastrointestinal — nausea, stomach cramps, and increased bowel movements — which can be reduced by taking with food. Not recommended during pregnancy. May interact with medications that increase acetylcholine levels (e.g. Alzheimer's medications). Use with caution in thyroid conditions, as bacopa may increase thyroid hormone levels.
Industrial hemp (low-THC cannabis) seed oil and seeds are generally safe as food. CBD products derived from hemp may interact with medications metabolised by cytochrome P450 liver enzymes, including common anticoagulants, antiepileptics, and immunosuppressants. THC-containing preparations impair driving and are regulated or prohibited in many jurisdictions. Not recommended during pregnancy or breastfeeding. Quality and cannabinoid content vary widely between hemp products.
Duke (2002) rates cannabis as ++ and notes clinical evidence (score 2) for its antiemetic activity, especially relevant for chemotherapy-induced nausea. Score 1 activities include analgesic, anticonvulsant, and anti-inflammatory properties. Duke highlights the legal and pharmacological complexity, noting THC as the primary psychoactive compound. Medically, synthetic cannabinoids (dronabinol, nabilone) are clinically approved for nausea and anorexia. Duke cautions that while the plant has genuine therapeutic potential, psychoactive effects, legal restrictions, and risk of dependence with regular use must be considered (Duke, 2002).

Botanical Description
Low, creeping, succulent perennial herb that roots at the nodes as it spreads across wet ground. The leaves are small, fleshy, spatula-shaped and arranged oppositely along the trailing stems. Small, pale lavender to white, four- to five-petalled flowers are borne singly in the leaf axils.[4]
Erect annual herb with a distinctive palmately compound leaf of narrow, serrated leaflets. The plant is usually dioecious (separate male and female plants); female plants develop dense, resinous flower clusters, while male plants bear looser pollen-releasing flowers. The seed (achene) is small, hard-shelled and oil-rich.[14]
Habitat
Grows in wet, marshy ground, muddy shorelines, rice paddies and shallow water throughout tropical and subtropical regions of Asia, and also found in parts of Africa, Australia and the Americas.[4]
Believed native to Central Asia; now cultivated worldwide, with industrial hemp (low-THC cultivars) grown in temperate climates for fibre, seed and cannabinoid extraction, subject to varying legal regulation by jurisdiction.[14]
Harvesting
The whole plant (leaf and trailing stem) is harvested during active growth, typically cut a few centimetres above the mud or water line, and dried or used fresh.
Flowers (and resin-bearing leaves) are harvested at peak resin/cannabinoid content, typically as the flower clusters mature in late summer to autumn; seed is harvested once mature and dried, then pressed for oil or used whole.[14]
Traditional Uses
Bacopa (brahmi) is a classic Ayurvedic 'medhya rasayana' (brain-nourishing) herb, traditionally used to support memory, learning and mental clarity, and as a calming nervine for anxiety and disturbed sleep. This traditional cognitive reputation is now supported by randomised controlled trials of standardised extracts.[1, 4]
Cannabis/hemp has a long multi-cultural history as a fibre, food and medicinal plant, traditionally used for pain, muscle spasm, sleep and appetite, alongside industrial use of the fibre and seed. Modern cannabinoid research, particularly on THC and CBD, has substantially expanded the evidence base for pain, spasticity and specific seizure disorders.[14, 15]
Preparations
Whole or hulled seed, or cold-pressed seed oil, used as a nutritional food source (essentially free of psychoactive cannabinoids).
Extract standardised to specific cannabinoid content (e.g. CBD), used in regulated medicinal products; regulatory status varies widely by jurisdiction and product type.
