IDENTIFICATION

Plant Morphology

Z. officinale var. rubrum is a slender perennial plant. Stem are dark green with a prominent midrib sheathed at the base with 30-60 cm in height; the second and later stems are shorter and terminate in flat bracts with few ancillary flowers. Leaves green in colour, narrow, 25-30 cm in length, 4-6 cm in width. Flower yellowish red in colour and are sparse. Rhizome red on the outside with a yellow to pinkish cross-section, base of its leaf shoot is red, branched, arranged laterally under the soil surface [ 2 ].

Microscopy

The abundant starch granules are almost all simple, of varying sizes from round to oval, oblong to sub rectangular in outline; compound granules with two components occur very rarely; the fibres are found in groups, sometimes found associated with the vessels, with thin dentate wall; the vessels are fairly large and scarce, usually found in groups, reticulate thickened frequently showing regularly arranged rectangular pits, spirally thickened vessels are much smaller and very few.

Clinical studies

A clinical trial to study the antiemetic effect of Z. officinale var. rubrum on chemotherapy-induced nausea and vomiting was conducted involving 20 cancer patients who were receiving chemotherapy CAF (cyclophosphamide, adriamycin-5-fluorouracil) and antiemetic drugs (ondasentron and dexamethasone).

Acute toxicity
Ethanol (95%) extract of Z. oficinale var. rubrum rhizome from administrated orally (2–5 g/kg) as a single dose to male and female Sprague Dawley rats (150-180 g body weight) for 14 days. No toxicity effect was observed in treated rats (LD50 value > 5 g/kg) [ 14 ].

Oral single dose acute toxicity study on female Sprague Dawley rats ( aged between 8 and 12 weeks old) using aqueous extract of E. elatior flowers showed no toxic effect on the parameters observed, including behaviors, body weight , food and water intake.
