Red thymes

Thyme oil Spanish red thyme oil) is obtained by steam distillation of flowering plants of T. zygis L. var. gracilis Boissier (Lamiaceae). Thyme oil is a red or reddish liquid with a strong, characteristic, spicy-phenolic odor and a sharp, lasting taste. 

Essential oils high in phenols that are skin irritants include cinnamon, clove, aniseed oil, basil, tarragon, red thyme and origanum. 

White thyme is not complete or natural, but is usually an adulterated and compounded oil made up of fractions of pine oils, rosemary, eucalyptus and red thyme, or it may be origanum with p-cymene, pinene, limonene and caryophyllene. 

All the materials tested were effective with the exception of boronia (Figure 4). Eucalyptus induced a 93% mortality, while cypress gave 90%, camphor 83% (Figure 2[10]), spearmint 78%, white thyme 75%, pheasant grass 50%, sassafras 50%, anethole (Figure 2[11]) 35%, red thyme 34%, and aniseed 28% (P < 0.05). It is interesting to note the disparity between white thyme and red thyme which indicates that either there is a significant increase in one bioactive compound in one cultivar versus the other, or that a specific ratio of compounds in the mixture is more effective than another. 

In comparing the results of Ae two sets of experiments, it will be seen that red thyme was 41% less effective against LBAM than white thyme and in controlling Flour Beetle there was, in comparison, a 65% difference between the two botanical cultivars. Furthermore, the effectiveness of the essential oils drops off rapidly so that only eucalyptus, camphor, and white thyme may be considered as useful canidates. Oddly, black pepper was inactive in these assays, while in earlier work certain components of this commodity have been shown to have strong insecticidal properties. The earliest report being in 1943 (12), which was followed not only by later reports of insecticidal...

Coal Tar.—These soaps contain, in addition to carbolic acid and its homologues, naphthalene and other hydrocarbons derived from coal, naphthol, bases, etc. Various blends of different fractions of coal tar are used, but the most valuable constituents from a disinfectant point of view are undoubtedly the phenols, or tar acids, though in this case as with carbolic and cresylic soaps, the amount of phenols should not exceed 3 per cent, in a toilet soap. An excess of naphthalene should also be avoided, since, on account of its strong odour, soaps containing much of it are unpopular. The odour of coal tar is considerably modified by and blends well with a perfum> containing oils of cassia, lavender, spike, and red thyme. 

Thymol,—This furnishes a not unpleasant, and very useful antiseptic soap, recommended especially for the cleansing of ulcerated wounds and restoring the skin to a healthy state. The normal strength is 3 per cent. It is preferable to replace part of the thymol with red thyme oil, the thymene of which imparts a sweeter odour to the soap than if produced with thymol alone. A suitable blend is 2 per cent, of thymol crystals and per cent, of a good red thyme oil. 

This oil is used in soap occasionally in place of red thyme oil. 

It is worth to note that both bacteriostatic and bactericidal concentrations of white thyme oil against E. coli (625 and 1,250 ttI/1, respectively) were two times lower than that of red thyme oil (Burt and Reinders 2003). 

The chemistry of thyme oil has been reviewed [219-223]. A gc-ms study of laboratory extracted L.CO2 and steam-distilled red thyme oil prepared from the same lot of leaves was reported by Bestman [224]. Of significant difference in composition of the two oils were, lower monoterpene hydrocarbons especially para-cymene and higher levels of free fatty acids Cig-Cig in the CO2 extract. 

Thyme oil is derived from T. vulgaris and T. zygis and its var. gracilis Boiss. Two types of thyme oil are produced, red thyme oil and white thyme oil. White thyme oil is obtained from red thyme oil by redistillation it has been reported to be much adulterated (arctander). The major oil-producing country is Spain (see also origanum, Spanish). 

Red thyme oil has been reported to be nonirritating, nonsensitizing, and nonphototoxic to human skin but severely irritating to mouse and rabbit skin when applied undiluted. ...
