Parts used:

Parts used as medicine are the whole plant except for the roots, harvested at the time the plants are out, dried or dried (Herba Ocimi).

Chemical composition:

The above ground part of the itas contains essential oils at the rate of 0.5% in the dry tree, the main ingredient of the essential oil is eugenol (accounting for about 70% of the total oil content).

Effects – the general use of Thyme:

Purple incense is used to treat colds, headache, stomach pain, diarrhea, vomiting, gas charges, perforation. Leaf color water used to rinse mouth to treat bad breath.

In which, eugenol is extracted to use as a local anesthetic, antiseptic, and used in dentistry to treat worn and numb teeth.

Some scientific researches on purple incense:

Antibacterial effect: 

  • In Vietnam, the antimicrobial effect of the essential oil of perilla oil has been experimented on by the Institute of Oriental Medicine on deep strains with evaluation by the sterile ring diameter. Bacillus mycoides has a sterile ring of 22 mm, B.subtilis is 60, Diplococcus pneumonia is 0 (ineffective), Escherichia coli is 15, Klebsiella sp is 12, Mycobacterium tuberculosis is 18, Proteus vulgaris is 18, Salmonella typlii is 22, Shigella dysenteriae is 30, Sh.flexneri is 12, Staphylococcus aureus is 20, Streptococcus haemolyticus is 15 (Excerpt: Department of Health – Scientific research work of medicine 1977-1989).
  • The Indian literature also mentions the antibacterial effects of basil essential oil on Mycobacterium tuberculosis. Bacillus pyocyaneus, Escherichia coli, Salmonella typhi and it was found that the antimicrobial effect on Mycobacterium tuberculosis of basil essential oil was about 1 / 10th of Streptomycin effect and 1 / 4th of isoniazid. In addition, the document also shows that purplish scent is effective against mosquitoes, so planting it around the house is considered a method of controlling mosquitoes (Source: The Wealth of India Vol VII – 1966 – 1984)

Anti-inflammatory, analgesic and antipyretic effects:

  • The methanol extracts and purplish emulsions have been tested for their anti-inflammatory, analgesic and antipyretic effects. The results showed that both dosage forms above have impact. In terms of anti-inflammatory, the dosage forms all have the effect of inhibiting edema of the liver and feet of white rats to cause carragenin on the model of acute inflammation and inhibition of the formation of riots, granulation in the model causing Chronic inflammation caused by injection of croton oil.
  • In both experiments above, anti-inflammatory effects of extracts and emulsions at a dose of 500 mg / kg as effective as sodium salicylate at a dose of 300 mg / kg.
  •  In terms of analgesic effects, in the experiment using hot-plate on white mice, methanol extracts and emulsion all have analgesic effects, in which extracts have stronger effects.
  • In addition, the extract also has the effect of prolonging the reaction time of morphine tail curvature in white rats.

– On animals causing fever by injecting typhoid and paratyphoid vaccines, methanol extract at a dose of 250 mg / kg and emulsion at a dose of 100 mg / kg both have antipyretic effects. However, the antipyretic effects of the two above forms have a weaker effect and a shorter duration than the effects of sodium salicylate at 300 mg / kg. Regarding the mechanism of these effects, some authors believe that it is at least partly due to the inhibitory effect on prostaglandin synthesis because the incense inhibits the diarrhea caused by castor oil in white rats. (J.of Ethnopharmacology 21- (1987) 15-3-163].

The essential oil is also proven to kill amib – Entamoeba moskowskii on culture medium with a concentration of 1: 1280 (Ministry of Health. Scientific and pharmaceutical research work 1977-1919). At the same time, essential oil has been shown to have antihistamine effects in guinea-pig isolation experiments (by the Ministry of Health. Research on Medicine and Pharmacy 1977-198).
