Analgesic and Antinociceptive Effects

In order to evaluate the analgesic and antinociceptive activity of Ajwain, an In vivo investigation was carried out using a Tail-flick Analgesiometer Device. The study revealed that the ethanolic extract significantly increase in Tail-Flick Latency (TFL) within 2 hours post-drug administration. An experimental trial study has also been carried out to compare the antinociceptive effect of the hydroalcoholic extract of Ajwain with morphine sulphate using formalin test. Findings revealed that Ajwain extract exhibited antinociceptive effect on both early and late phases. Similar study has been done on the Ajwain total essential oil which was significantly effective on the late phase of formalin test and it may be due to the presence of thymol in essential oil.

In addition, under a randomized controlled placebo control clinical trial, the herb essential oil was assayed for the analgesic effect in neuropathic feet burn. Results revealed that Ajwain essential oil significantly reduced the feet burn compared to placebo.

Gastro protective activity

Ajwain (Trachyspermum ammi) seed menifest anti-ulcer activity. Animals pre-treated with ethanolic extract exhibit remarkable decrease in ulcer protection per cent and ulcer index in all models. The findings inferred that the extract showed significant protection by reducing ulcerative lesions when compared with control group of animals.

Hepatoprotective activity

The results revealed that hepatoprotective actions in vivo of ajwain was 80% protective in mice against a normally-lethal dose of paracetamol (1 g kg–1), it prevented the CCl4¯ induced prolongation of pentobarbital sleeping time in mice and it tended to normalize the high serum levels of liver enzymes caused by CCl4¯ induced liver damage in rats.

Anti-inflammatory effects

The ajwain fruits have observed anti-inflammatory potentials against rat models (Carageenan induced rat paw oedema) and subacute rat model (Cotton pellet induced granulluma) they used aspirin 150mg/Kg and Phenyl butazone 150mg/Kg as control. In the acute model, Aspirin and Phenyl Butazone (PBZ) showed an inhibition of 45.23% and 43.83% respectively.

Detoxification of aflatoxins

The seeds extract of trachyspermum ammi reflect the maximum degradation of aflatoxin G1 (AFG1). The aflatoxin detoxifying activity was reduced on boiling the fruits or seeds. It is also observed that significant level of degradation of other aflatoxin viz., AFB1, AFB2 by dialyzed seeds extract. Time course study of AFG1 detoxification by dialyzed T. ammi extract showed that more than 91% degradationoccurred at 24 hours and 78% degradation occurred within 6hours after incubation.

Lessen Greying of Hairs

Ajwain helps in lessening premature graying of hairs. Cook curry leaves + dry grapes + ajwain in a cup of water and drinks the mixture every day to prevent pre maturation of hairs.

Relief from Arthritis Pain

Ajwain has antibiotic properties, thus helping in reducing redness and combat inflammation. They also have anesthetic properties that give relief from pain and swelling. Apply the paste of crushed ajwain seeds to joints or soak in a tub of warm water with the hand full of ajwain seeds in it to get relief.

Antibacterial and Antifungal Activities

To assay the antibacterial efficacy of Ajwain, acetone and aqueous extracts were tested against Enterococcus faecalis, Escherichia coli, Klebsiella pneumonia, Pseu-domonas aeruginosa, Salmonella typhi, Salmonella typhi-murium, Shigella flexneri, and Staphylococcus aureus using agar diffusion assay. The study showed that acetone extract shows more activity compared to the aqueous extract.

In another study, ethanolic extract of Ajwain possessed antibacterial activity against eight strains of Helicobacter pylori. Also methanolic extract of Ajwain exhibited bactericidal activity against 11 species at 2mg/well in agar well-diffusion method. It was measured by Diameter of Inhibition Zones (DIZ). DIZ was over 15mm against Staphylococcus aureus and Staphylococcus epidermidis; 10–14 mm against Pseudomonas aeruginosa and Bacillus pumilus; 7–9 mm against Escherichia coli, Klebsiella pneumonia as well as Bordetella bronchiseptica. On the other hand, no activity was reported against Pseudomonas fluorescens and Micrococcus luteus. As Ajwain may have large amounts of Thymol or Carvacrol in its total essential oil, mentioned phenolic compounds are reported to be either bactericidal or bacteriostatic agents depending on the concentration.

In order to assess the antifungal activity of Ajwain, total essential oil extracted from seeds was subjected for fungicidal effect and showed proper effect on Aspergillus niger and Curvularia ovoidea at 5000 ppm as minimum inhibitory concentration

Antioxidant activity

The seeds of ajwain exhibited antioxidant activity by using ABTS and DPPH assay methods, ferric reducing antioxidant power and total phenolic content. The ethanolic extract of T. ammi shows activity against hexachloro cyclohexane (HCH) induced lipid peroxidation.


Antihypertensive and broncho-dilating property

The antihypertensive effect of Trachyspermum ammi administered intravenously in vivo and the antispasmodic and broncho-dilating actions. In vitro showed that calcium channel blockade has been found to mediate the spasmolytic effects of plant materials and it is being considered that this mechanism contributed to their observed result and supported the traditional use of Trachyspermum ammi in hyperactive disease states of the gut such as colic and diarrhea as well as in hypertension

Hypolipidemic action

In albino rats antihyperlipidemic effect of ajwain seed has been obtained. It was assessed that powder made by ajwain seed at a dose rate of 2 g kg–1 body weight and its equivalent methanol extract were extensively effective in lipid lowering action by decreased LDL-cholesterol, total cholesterol, triglycerides and total lipids

Abortifacient and galactogogic action

There is a high risk of potential human foetus toxicity of ajwain, based on teratogenicity find in rat fetuses. It has been traditionally used as a galactogogue in humans. The total phytoestrogen content of dry ajwain seed or fruits was 473ppm, which was the second highest in the list of eight herbs tested.
