Syrian Rue has carved its name into the chronicles of time. Leonardo da Vinci and Michelangelo both used Syrian Rue – also known as Peganum Harmala.  Da Vinci said Syrian Rue is “miracle smart nutrient”. In the Middle East it is known as Esfand and is used as incense to cleanse a room of evil.  Most references to Syrian Rue in Persian history involve the use of magic.  Greeks refer to it as Persaia botane.  Shakespeare referred to it in his writings, although his personal use of it is unknown.  Smoke from Rue Seeds was used in several ancient religious rituals.  It has been found in the hair of mummified bodies in Egypt. When whole seeds are placed on hot charcoals the seeds explode like popcorn, releasing a fragrant smoke.  In the ancient world it was known as the “Soma Plant”.  Mention has also been made of its ability to antidote the poison of a snake bite.  Dioscorides includes not only reptile poisons but all deadly poisons, including poison mushrooms, scorpions, spiders, and mistletoe.  Pliny notes that weasels about to fight with snakes first protect themselves by eating Syrian Rue. It is also good for fevers with rigors(chills).  Serapio calls it ‘the ultimate medicine against the evil of poisons’.  Dodoens, Gerard, Bauhin, Parkinson and Culpeper want it as a remedy against the plague. Syrian Rue was used by thieves who robbed the houses of plague victims under the protection of their aromatic repellent.  It is also known as the “anti-plague” plant.  After the assignation of his father by poison, Mithridates King of Pontus studied poisons and used Syrian Rue.

In addition to all the ancient documentation about Syrian Rue, more recent scientific observations from research teams around the world (fully referenced below) prove that the fluorescent harmala beta-carboline alkaloid combied with all the other alkaloids in Syrian Rue is arguably magical or contains a synergy of alkaloid crystals at a frequency with proper phase conjugation which is responsible for the unusual combination of it being antibacterial, antiviral, and antiparasitic, as well as antimutagenic and antigenotoxic.

In 2007 it was first proposed that Syrian Rue might help with diabetes, by 2015 independent studies are reporting success with Rue, in 2017 now we know Type 2 diabetics might be able to achieve a reversal of their condition and Type 1 diabetes patients are able to produce healthy new pancreatic beta cells.


The extract of Peganum harmala was used topically to treat certain dermatoses of inflammatory nature. Results were encouraging and proved the antibacterial, antifungal, antipruritic and probably antiprotozoal effects of the extract.

P harmala seeds extract showed significant in vitro and in vivo antileishmanial activities. Cutaneous leishmaniasis (CL), an endemic disease in many tropical and subtropical areas, including central and southern parts of Iran, continues to present serious treatment problems. The disease, although usually self-limiting, can cause considerable morbidity and may result in severe disfigurement.  P. harmala, vasicine (peganine), has been found to kill the protozoan parasite Leishmania donovani.

P. harmala has appreciable efficacy in destroying intracellular parasites in the vesicular forms.   Because of its appreciable efficacy in destroying intracellular parasites as well as non-hepatotoxic and non-nephrotoxic nature, harmine, in the vesicular forms, may be considered for clinical application in humans.

Peganum harmala seed extracts also show effectiveness against various tumor cell lines, both in vitro and in vivo.  Results obtained indicate that alkaloids of Peganum have a high cell toxicity in vitro. The active principle at a dose of 50 mg/kg given orally to mice for 40 days was found to have significant antitumoural activity. Peganum harmala alkaloids thus possess significant antitumour potential, which could prove useful as a novel anticancer therapy.

Plant derived agents may exert a new approach to the treatment of leukaemia. The present study was an evaluation of proliferation, cytotoxicity and differentiation of harmine and harmaline on HL60 cells, alone or in combination with ATRA and G-CSF. Counting of cells, viability, MTT assay, morphology, NBT reduction and flow cytometry analysis were performed using CD11b and CD 14 monoclonal antibodies. The data showed that harmine and harmaline reduced proliferation in dose and time dependent manner.  This shows that the direction of differentiation is dominantly determined by ATRA. These preliminary data implies a new approach in treatment of leukemia.

The beta-carboline alkaloids present in medicinal plants, such as Peganum harmala and Eurycoma longifolia, have recently drawn attention due to their antitumor activities. Further mechanistic studies indicate that beta-carboline derivatives inhibit DNA topoisomerases and interfere with DNA synthesis. Moreover, some beta-carboline compounds are specific inhibitors of cyclin dependent kinases (CDKs). In this study we used budding yeast as a model system to investigate the antitumor mechanism of beta-carboline drugs. We found that DH334, a beta-carboline derivative, inhibits the growth of budding yeast.Cancer and Biological Therapy,  2007 Aug;6(8):1193-9. Epub 2007 May 4.

We report the in vivo antioxidative properties of the aromatic (harmane, harmine, harmol) and dihydro-beta-carbolines (harmaline and harmalol) studied by using Saccharomyces cerevisiae strains proficient and deficient in antioxidant defenses. Their antimutagenic activity was also assayed in S. cerevisiae and the antigenotoxicity was tested by the comet assay in V79 cell line, when both eukaryotic systems were exposed to H(2)O(2). We show that the alkaloids have a significant protective effect against H(2)O(2) and paraquat oxidative agents in yeast cells, and that their ability to scavenge hydroxyl radicals contributes to their antimutagenic and antigenotoxic effects.

A 2016 study investigated the antimicrobial activity of Harmal ( Peganum harmala) aqueous extracts against two fungi (Aspergillusniger and Peniciliumitalicum) and two Gram negative bacteria (Escerichia coli and Salmonellatyphi). The Harmal methanolic extracts were found to inhibit mycelial radial growth of both fungi. This effect was found to be significant at first day of the experiment as well as the last days. Mycelial fresh and dry weights of both fungi were also greatly reduced with harmal extracts. The higher concentration of Harmal gave the maximum effect which decreased with dilution. The effect on mycelial growth was more pronounced on P.italicum than on A.niger. The effect of Harmal leaves extract on the two bacteria (E.coli and S.typhi) was evaluated by the inhibition zone and dilution methods. A clear zone of inhibition was shown by the extracts against both bacteria, although the inhibition was less against E.coli. The results of the dilution plate method showed that the log number of colonies of both bacteria was highly decreased with Harmal extract; however, S.typhi was more susceptible and greatly affected by the extract.

According to test results, P. harmala seeds extract showed potent antioxidant activity with IC50 values ranging between 40-129 µg/ml. In case of antibacterial assay, P. harmala seeds showed better inhibitory activity than leaves against both strains i.e. Staphylococcus aureus and Pseudomonas aeruginosa with values ranging between 70 to 100% while in case of antifungal assay water-acetone extract of seeds showed significant antifungal effect against Aspergillus niger. In terms of cytotoxic assay, hexane extract of seeds of were more cytotoxic against shrimp larvae (LD50 = 57.07 µg/ml). Aqueous extract of leaves of and acetone extract of seeds showed < 80% mortality in antileishmanial assay. GC-MS analysis revealed that leaves and seeds contain some important biological metabolites. It is concluded that selected plants could be a potential source of antileishmanial, antibacterial, antifungal and anticancer lead compound. Hence it is indicated to further investigate this plant in vitro as well as in vivo for new drug discovery.

Introduction: Benign prostatic hyperplasia (BPH) is considered as a major cause of lower urinary tract symptoms (LUTS) in older men and its most common sign is nocturia. Objectives: This study aimed to determine the effect of the seeds of Peganum harmala compared with tamsulosin on alleviating urinary symptoms in patients with BPH. Patients and Methods: In this single blind clinical trial study, 90 patients diagnosed with BPH and LUTS, based on international prostate standard survey (IPSS) were divided into three groups. The first group was received oral capsule of P. harmala, the second group was administered tamsulosin with oral P. harmala seed and the third group was received tamsulosin drug and they were evaluated after 4 weeks. Results: The results showed that the difference between mean scores of IPSS was significant after the intervention (P=0.001). Besides, the mean of IPSS in the three groups was significantly different (P=0.001) (the first group 41.9±5.3, the second group 21.0±4.4 ,the third group 16.5±3.7 respectively). However, after the intervention, patients in the second group had the lowest average on most indicators of IPSS but the difference was only significant about urinary frequency, nocturia and intermittency(P<0.05). Conclusion: Application of Peganum harmala seed can be useful in reducing urinary symptoms in patients with BPH.

A 2016 study found that Syrian Rue fights dental plaque.  An ethanolic extract of P. harmala can inhibit the growth of S. mutans. Despite the higher inhibitory effect of 0.2% chlorhexidine compared to 50 mg/mL of this extract, other studies indicate that higher concentrations of P. harmala extract can have similar or greater inhibitory effect against microorganisms. However, high cell toxicity of this extract on cells limits the use of this plant as an antimicrobial agent (like mouthwash) in oral cavity. Even if limited to low concentrations, either lonely or in combined preparations, its application might be more useful for resistant bacteria compared to the routine available mouthwashes. Further antimicrobial and cytotoxicity studies on animals or human subjects are needed to obtain more accurate and applicable results.

The cytotoxic effects of peganum harmala were evaluated on six malignant cancer cells. Total alkaloids of the different parts were cytotoxic towards practically all cancer cell lines with IC50 ranging 1–52 µg/mL after 72 h of treatment. These data indicate that P. harmala alkaloids extract may support the traditional claims regarding its anticancer uses which could be helpful in providing of new cytotoxic agents against chemo-resistant cancer cells.
