Clinical monograph: beet
Beet, commonly known as beetroot, is a root vegetable belonging to the family Amaranthaceae. It is rich in vitamins, minerals, and antioxidants, particularly betalains, which contribute to its deep red color. Beets are often consumed in various forms, including raw, cooked, or as juice, and are known for their potential health benefits, including supporting cardiovascular health and improving exercise performance.
Indications
- Hypertension
- Improvement of exercise performance
- Cardiovascular health support
- Potential anti-inflammatory effects
Dosage
Children: There is no specific pediatric dosage for beetroot; it can be introduced as part of a balanced diet, considering the child's age and tolerance.
Adults: There is no standard adult dosage for beetroot as a food product, but commonly, 250-500 mL of beet juice is consumed daily for health benefits.
Mechanism of action
The primary active components in beets are nitrates, which are converted in the body to nitrites and then to nitric oxide. Nitric oxide is a vasodilator, meaning it relaxes and widens blood vessels, improving blood flow and reducing blood pressure. This mechanism is particularly beneficial in enhancing exercise performance and cardiovascular health.
Pharmacodynamics
The pharmacodynamics of beetroot are largely attributed to its high nitrate content. Upon ingestion, dietary nitrates are metabolized to nitrites by oral bacteria and subsequently converted to nitric oxide in the gastrointestinal tract and bloodstream. The increased levels of nitric oxide lead to vasodilation, improved oxygen delivery to tissues, and enhanced exercise efficiency. The antioxidant properties of betalains also contribute to the anti-inflammatory effects observed with beet consumption.
Pharmacokinetics
After consumption, dietary nitrates from beet are rapidly absorbed in the stomach and small intestine. Peak plasma concentrations of nitrates are typically reached within 1-2 hours. The conversion of nitrates to nitrites occurs primarily in the mouth through bacterial action, with further conversion to nitric oxide happening in the body. The half-life of nitric oxide is very short, but its effects can last for hours depending on the dose and individual response. Excretion of nitrates and nitrites occurs via urine.
Adverse effects
- Red urine (beeturia)
- Gastrointestinal discomfort
- Diarrhea
- Nausea
- Hypotension (in rare cases)
Precautions
- Patients with kidney stones should exercise caution, as beetroot is high in oxalates.
- Monitor blood pressure in patients with hypotension.

It has been shown to enhance the production of nitric oxide, leading to vasodilation and improved blood circulation. Additionally, garlic may exert antioxidant effects by scavenging free radicals and enhancing the body's antioxidant defenses.
Pharmacodynamics
Garlic has been associated with a range of pharmacodynamic effects. It can reduce platelet aggregation, thereby lowering the risk of thrombosis. Garlic also modulates lipid metabolism, which may contribute to its cholesterol-lowering effects. Furthermore, it has anti-inflammatory properties that may benefit conditions such as arthritis. The bioactivity of garlic is influenced by factors such as preparation methods and the presence of certain phytochemicals.
Pharmacokinetics
The pharmacokinetics of garlic compounds can vary significantly based on the form in which they are consumed (raw, cooked, aged extracts, etc.). Allicin is rapidly formed upon crushing garlic and can be absorbed in the gastrointestinal tract, though it is also quickly metabolized. The half-life of allicin is relatively short, leading to transient effects. Other compounds derived from garlic, such as ajoene and diallyl disulfide, may have longer-lasting effects in the body. Garlic is generally well-tolerated, but can cause gastrointestinal upset in some individuals.

Dosage
Children: Pediatric dosing should be determined based on clinical guidelines and individual patient factors. It is essential to consult appropriate pediatric dosing references.
Adults: Dosage should be individualized based on clinical response, renal function, and serum concentration monitoring. Refer to specific guidelines for dosing considerations.
Mechanism of action
The active compounds in purpurea, such as digoxin, exert their effects by inhibiting the Na+/K+ ATPase pump in cardiac myocytes. This inhibition leads to an increase in intracellular sodium concentrations, which in turn promotes calcium influx via the sodium-calcium exchanger. The increased calcium levels enhance contractility of the heart muscle (positive inotropic effect), and also help to regulate heart rate by increasing vagal tone and decreasing conduction through the atrioventricular node.
Pharmacodynamics
Purpurea exhibits positive inotropic effects, increasing the force of myocardial contraction, which is beneficial in conditions like heart failure. It also has a negative chronotropic effect, helping to slow down a rapid heart rate. The therapeutic window for the active compounds is narrow, making monitoring of serum levels essential to avoid toxicity.
Pharmacokinetics
The bioavailability of digoxin, one of the primary active ingredients from purpurea, is approximately 60-80% when taken orally. It is primarily eliminated through renal pathways, with a half-life of approximately 36-48 hours in patients with normal renal function. The distribution volume is extensive due to its binding to tissues, particularly cardiac tissues. Factors such as renal function, age, and body weight can significantly affect the pharmacokinetics of purpurea-derived compounds.
Pregnancy
The safety of purpurea during pregnancy has not been established. It is advised to avoid use unless the potential benefits outweigh the risks.
Breast-feeding
Due to lack of data on the excretion of purpurea in breast milk, caution is recommended when used while breastfeeding.
Storage

Molecular reference: tumeric
PubChem CID 969516Molecular formula: C21H20O6
Mechanism of action
Curcumin acts as a scavenger of oxygen species, such as hydroxyl radical, superoxide anion, and singlet oxygen and inhibit lipid peroxidation as well as peroxide-induced DNA damage. Curcumin mediates potent anti-inflammatory agent and anti-carcinogenic actions via modulating various signalling molecules. It suppresses a number of key elements in cellular signal transduction pathways pertinent to growth, differentiation, and malignant transformation; it was demonstrated _in vitro_ that curcumin inhibits protein kinases, c-Jun/AP-1 activation, prostaglandin biosynthesis, and the activity and expression of the enzyme cyclooxygenase (COX)-2. Curcumin, a polyphenolic natural product, exhibits therapeutic activity against a number of diseases, attributed mainly to its chemical structure and unique physical, chemical, and biological properties. It is a diferuloyl methane molecule [1,7-bis (4-hydroxy-3- methoxyphenyl)-1,6-heptadiene-3,5-dione)] containing two ferulic acid residues joined by a methylene bridge. It has three important functionalities: an aromatic o-methoxy phenolic group, alpha, beta-unsaturated beta-diketo moiety and a seven carbon linker. Extensive research in the last two decades has provided evidence for the role of these different functional groups in its crucial biological activities. A few highlights of chemical structural features associated with the biological activity of curcumin are: The o-methoxyphenol group and methylenic hydrogen are responsible for the antioxidant activity of curcumin, and curcumin donates an electron/ hydrogen atom to reactive oxygen species. Curcumin interacts with a number of biomolecules through non-covalent and covalent binding. The hydrogen bonding and hydrophobicity of curcumin, arising from the aromatic and tautomeric structures along with the flexibility of the linker group are responsible for the non-covalent interactions. The alpha, beta-unsaturated beta-diketone moiety covalently interacts with protein thiols, through Michael reaction. The beta-diketo group forms chelates with transition metals, thereby reducing the metal induced toxicity and some of the metal complexes exhibit improved antioxidant activity as enzyme mimics. New analogues with improved activity are being developed with modifications on specific functional groups of curcumin... The present study demonstrates that curcumin acts as pro-oxidant and sensitizes human lung adenocarcinoma epithelial cells (A549) to apoptosis via intracellular redox status mediated pathway. Results indicated that curcumin induced cell toxicity (light microscopy and MTT assay) and apoptosis (AnnexinV-FITC/PI labeling and caspase-3 activity) in these cells. These events seem to be mediated through generation of reactive oxygen species (ROS) and superoxide radicals (SOR) and enhanced levels of lipid peroxidation. These changes were accompanied by increase in oxidized glutathione (GSSG), reduced glutathione (GSH) and gamma-glutamylcysteine synthetase (gamma-GCS) activity, but decrease in GSH/GSSG ratio. The induction of apoptosis and decrease in GSH/GSSG ratio was also accompanied by sustained phosphorylation and activation of p38 mitogen activated protein kinase (MAPK). On the other hand, addition of N-acetyl cysteine (NAC), an antioxidant, blocked the curcumin-induced ROS production and rescued malignant cells from curcumin-induced apoptosis through caspase-3 deactivation. However, L-buthionine sulfoximine (BSO), a GSH synthesis blocking agent, further enhanced curcumin-induced ROS production and apoptosis in A549 cells. Decreased GSH/GSSG ratio seems to be a crucial factor for the activation of MAPK signaling cascade by curcumin. The study therefore, provides an insight into the molecular mechanism involved in sensitization of lung adenocarcinoma cells to apoptosis by curcumin. Curcumin has many pharmaceutical applications, many of which arise from its potent antioxidant properties. The present research examined the antioxidant activiti
Pharmacodynamics
Intravenous application of 25 mg/kg bw curcumin to rats resulted in an increase in bile flow by 80 and 120%. In the rat model of inflammation, curcumin was shown to inhibit edema formation. In nude mouse that had been injected subcutaneously with prostate cancer cells, administration of curcumin caused a marked decrease in the extent of cell proliferation, a significant increase of apoptosis and micro-vessel density. Curcumin may exert choleretic effects by increasing biliary excretion of bile salts, cholesterol, and bilirubin, as well as increasing bile solubility. Curcumin inhibited arachidonic acid-induced platelet aggregation _in vitro_.
