Alka Melt Drops Ingredients

The material behind this name is a leaf extract standardised to its total triterpenic fraction, usually abbreviated TTFCA and made up of asiaticoside, asiatic acid and madecassic acid. That fraction is the reason the plant has a dose-response at all, and it is what the chemistry and pharmacology review tracks through the literature. A row that printed “standardised to 40 per cent triterpenes” would be checkable; a row that prints only the plant name is not.

Hawthorn material is sold either as a fruit extract or as a leaf-and-flower extract, and the cardiac research is built almost entirely on one standardised leaf-and-flower preparation. The seller prints fruit. That is a legitimate material with its own traditional use, and it is not the one the dose-comparison trial ran. The marker to look for on a checkable row would be a procyanidin or flavonoid percentage.

The only material on either list whose active fraction has an agreed name, an agreed assay and an agreed daily figure. Seed extract is standardised to escin, and the escin review describes the anti-oedema and venotonic pharmacology behind it. Because that convention exists, a label printing “horse chestnut seed extract, standardised to 16 to 20 per cent escin” tells a reader almost everything. This one prints the name.

A North American mint-family root with a long place in nineteenth-century eclectic practice and essentially no modern pharmacology. There is no accepted marker compound, no monograph, no assay and no standardised commercial material with a stated potency. It is the one name here where even a printed milligram figure would not make the row checkable, because there would be nothing to check it against.

Aerial parts are cut above ground at flowering, and the characteristic constituents are the iridoid glycosides and alkaloids the pharmacological review catalogues. The single clinical study used an oil extract, which is a specific and fairly unusual preparation rather than the common dried herb or hydroalcoholic tincture. Preparation, not just plant part, is the variable here.

Root and rhizome, standardised where it is standardised at all to ruscogenins, the steroidal saponins that carry its venous activity. A 2022 review of ruscus and leg oedema covers the material and the preparations in commerce. The awkwardness with this one runs deeper than a missing figure: even its own trial states a monograph dose rather than a number.

Seed, not skin, and the distinction matters commercially: skin extracts are sold for resveratrol and seed extracts for oligomeric proanthocyanidins. Seed material is usually standardised to a proanthocyanidin percentage, and the pooled blood-pressure work draws on preparations described that way. NCCIH is the plainest summary of where the evidence sits overall.

The one row on either list where the active is a simple molecule at a known concentration. Table vinegar runs at about 5 per cent acetic acid, so the 15 mL and 30 mL doses in the 12-week trial correspond to roughly 750 mg and 1,500 mg of acetic acid a day. Those are gram quantities, which is the fact that makes a 60 mL dropper bottle an awkward vehicle for them.

A single synthesised compound rather than an extract, which means there is no plant part, no extract ratio and no standardisation question. Purity and amount are the only two variables, and this label states neither. The best-controlled animal study is the reason it appears on the mechanism page under a proposed pathway rather than a demonstrated one.

Root material standardised, where it is, to diosgenin. Diosgenin is a starting material that chemists convert to steroid hormones in a factory, and the human body does not perform that conversion. That single fact explains both why the ingredient became popular and why the one proper trial found nothing moving.

Unripe fruit, usually dried and powdered or extracted, and sold in forms that range from juice to a concentrated extract with very different potencies. The 2,000 mg-a-day trial used a specific preparation over three months. Without a form and a figure, a row reading “bitter melon extract” could be anything from a flavouring trace to a clinical amount.
