Siwak, Chemical Composition and Benefits – Including three research Papers

1 – Recent laboratory researches indicate that Siwak prepared from and contains a large portion of (gall), an anti-mildew substance and an antiseptic astringent that stops bleeding of gum and strengthens it.“It is of….acrid taste that kills bacteria”

2-Researches emphasize that there is a mustard substance called sinnigrin”

3 – Dr. Tariq Al Khoury affirmed the existence of chloride and silica which increase the degree of whiteness of teeth, and there is a  gum substance covering enamel and protects teeth from caries.

4 – There is also “methylamine” that helps the recovery of gum and helps it grow properly. It is an antiseptic that can adapt “PH” of the oral cavity in a way that affects “indirectly” in the growth of microbes, researchers found also other quantities of anti-tumor.

5 – After scrutinizing the Siwak stick and investigating its components and its medical value, it was found that it contains a good amount of Florin that makes teeth strong and resistent to acid effect of caries, the main role of Florin is clear in the stage of growth and formation of teeth as the element goes strongly into it to replace other atoms that are less reactive such as potassium and sodium in the inner parts of enamel and makes atomic bonds formed by the new substance that are more strong than the bonds of less reactive elements.Moreover, the exposure of enamel to florin at this stage transforms it from “hydroxyapatite” to another strong form that is “fluroapatite”.6 – Other than florin, there is an amount of chlorine that removes tincture , and silica  that has a known role in protecting teeth.

7- there is a substance called “silica” of about 4% of Siwak stick that has a characteristic to scrape and remove plaque.

8 – Also it is worthy mentioning sodium bicarbonates which  teeth healing assembly at American Dental Association recommended adding when healing teeth

9 – There is a substance called “silva urea” in Siwak which is known for its ability to prevent caries and necrosis and therefore protects the formation of aforementioned areas of abscess.

10 – When analyzing Siwak stick, We found there is an amount of ansinic acid that helps in throwing out phlegm from the chest as well as an amount of ascorbic acid and citocitrol, both can strengthen arterial capillaries of the gum.

The aim of the study was to compare the effect of the chewing stick (miswak), and toothbrushing on plaque removal and gingival health.


The participants comprised 15 healthy Saudi Arabian male volunteers aged 21 to 36 years, attending the Dental Center at Al-Noor Specialist Hospital in Makkah City in Saudi Arabia. The study was designed as a single, blind, randomized crossover study. The Turesky modified Quigley-Hein plaque and Löe-Silness gingival indices and digital photographs of plaque distribution were recorded at baseline, one week after professional tooth cleaning, and again following three weeks use of either the miswak or toothbrush. Professional tooth cleaning was repeated, and after a further three weeks use of either the miswak or toothbrush (using the alternative method to that used in the first experimental period), plaque and gingival indices, and digital photographs of plaque distribution were recorded anew.


Compared to toothbrushing, the use of the miswak resulted in significant reductions in plaque (p < 0.001) and gingival (p < 0.01) indices. Image analysis of the plaque distribution showed a significant difference in reduction of plaque between the miswak and toothbrush periods (p < 0.05).


It is concluded that the miswak is more effective than toothbrushing for reducing plaque and gingivitis, when preceded by professional instruction in its correct application. The miswak appeared to be more effective than toothbrushing for removing plaque from the embrasures, thus enhancing interproximal health.

The chewing stick, the miswak, is used in many developing countries as the traditional means for oral hygiene. It is prepared from the roots, twigs and stem of Salvadora persica or other alternative local plants.


To compare the effects of the chewing stick miswak (from S. persica) and toothbrush on subgingival plaque microflora among Saudi Arabian individuals. Further, to investigate whether components extracted from S. persica may interfere with the subgingival plaque micro-organisms.


Fifteen healthy Saudi Arabian male volunteers aged 21-36 years were included in a single-blind, randomized cross-over study. The participants were taught how to use each device properly. Plaque sampling for DNA test was performed at the baseline, 1 week after professional tooth cleaning, and after 3 weeks of either miswak or toothbrush use. Identification and quantification of microbial species were performed by the checkerboard method, using whole genomic, digoxigenin-labelled DNA probes. Inhibition zones around miswak were examined on agar plates with Actinobacillus actinomycetemcomitans and the leukotoxicity of this bacterium was analyzed in a bioassay with macrophages+/-extracts of miswak.


Miswak and toothbrushing had a similar influence on the levels of the subgingival microbiota. However, A. actinomycetemcomitans was significantly more reduced by miswak (p<0.05) than by toothbrushing. These results were supported by our in vitro results which, indicated that extracts from S. persica might interfere with the growth and leukotoxicity of A. actinomycetemcomitans.


In contrast to toothbrush use, miswak use significantly reduced the amount of A. actinomycetemcomitans in the subgingival plaque.
