Sisymbrium “Singers’ Plant” Efficacy in Reducing Perceived Vocal Tract Disability

Authors:

Abstract

Sisymbrium officinale is a plant used since Greeks Medicine in vocal tract diseases to reduce disability derived from dryness, sore throat, cough,... Modern Phytopharmacology is standardizing active principles in this plant, but still few works in literature describe results known in traditional medicine.A small group of patients treated with Sisymbrium at recommended doses described the perceived physical disability pre and post treatment by VHI (Voice Handicap Index) scores. Analysis of the difference (delta) between VHI scores seems to prove Sisymbrium efficacy in reducing perceived disability, so facilitating voice use. In this way Sysimbrium results a choice to solve patients’ discomfort, reserving “classical” treatments - NSAIDs and antibiotics - to major pathologies.Keywords: Vocal tract; Erysimum; Sisymbrium officinale; VHI; Phytotherapy

author of Historia generalis plantarum, wrote that his master
Guillaume Rondelet “professeur royal de médecine à Montpellier”
gave it to a young choir singer, who promptly regained his voice.
Fernie [1] cited that, up to the time of Louis XIV, Racine wrote to
Boileau to recommend him Erysimum syrup in order to be cured
of voicelessness :“Si les eaux de Bourbonne ne vous guerissent pas
de votre extinction de vois, le syrop d’Erysimum vous guerirait
infalliblement. Ne l’oubliez pas, et a l’occasion vingt grammes par
liter d’eau en tisane matin et soir“. Tradition says that Racine gave
this advice because he knew a singer, voiceless since 6 months,
helped by erysimum to regain his voice and sing in front of the
King in Notre Dame Cathedral.
In the International Plant Name Index 1, the plant name was
given in 1772 by Giovanni Antonio Scopoli [2]. He wrote it in
Flora Carniolica, a book to describe plants of his region (now in
Northern Italy, between Trentino and Friuli regions). Scopoli was
called “the Linnaeus of the Austrian
Empire”: indeed he and Linnaeus were corresponding and
Linnaeus named a solanaceous genus, Scopolia, the source of
scopolamine, after him.
Traditional medicine recommends using the semi-fresh

a) The medicinal use of hedge mustard preparation is considered
safe because no adverse effects have been reported during
the long-standing use as a medicinal product in Belgium and
Germany.
b) The known toxic cardioactive steroid glycosides have been
documented as a minor component and their concentrations
are too low to present any risk to human health.
c) The oromucosal use in children under 6 years of age is not
recommended because of the solid dosage form and due to
lack of adequate data.
d) The oral use in children under 3 years of age is not
recommended due to lack of adequate data and because, for
the proposed indication, medical advice should be sought for
this age group.

A widespread used method to assess perceived Voice Handicap

al. [15], where handicap is measured through three different
scales measuring Physical, Functional and Emotional perceived

tract is physically disabling. The scores delta, between pre and

Materials and Methods
Only France and Germany have products registrated for
traditional use [16]. In this work the Authors used French product
Sisymbrium. In random serie, patients claiming vocal tract
discomfort were treated with Sisymbrium, 90 mg extract/day for
10-20 days, [16] alone or with treatment related to the diagnosed
disease [17].
Diagnosis was described as: Functional Dysphonia (FD),

The Patients were 64 F and 40 M, aged 8-80 yrs -mean age
42,1yrs. They were 65 artists (A), 30 non artists (NA) and 9 Voice
Professionals in spoken non artistic voice (VP). 3 of them did not
submit to controls (NA) so the studied group was of 62 F, 39 M; 63
A, 30 NA, 8 VP. Their diagnosis distributed as 20 FD, 21 OD, 5 LPR,
14 LPR + OD, 32 UAAF, 13 UACF.
Results
i. The mean VHI-P pretreatment score was 27, 9 /40: pretty high
level of perceived disability. The mean VHI-P post treatment
score was 13, 2: a very low level of residual disability.
ii. The average DELTA VHI was around 14/40: this means the
reduction of one third of the perceived disability in a short
time.
iii. In FD the treatment with Sisymbrium obtained a mean
reduction of disability of 13/40.
iv. In OD the result was 13, 6/40 in Sisymbrium alone treatment,
while in 10 days complex treatment the reduction was 13/40
and in 20 days 14, 4/40.
v. In LPR the treatment with added Sisymbrium gave a mean
reduction of 12/40 in a 10 days treatment and 13, 9/40 in a
20 days treatment.
vi. In UAAF treated with Sisymbrium the mean perceived
reduction was 15/40, 14, 9/40 in 10 days combined and 15,
6/40 in 20 days combined.
vii. In UACF treated with Sisymbrium plus FANS for 20 days, the
referred reduction of perceived disability was 13, 2/40 avg.

effect does not look similar to NSAIDs, like salycilates [18-20].
In our work the main claim is physical disabling effect of
dryness, related to hyperemia and sticky secretions. The effect of
Sisymbrium seems mostly “moisture enhancing”, - and in this case
tissues’ weights should not change that much, or better increase
than decrease.
The scores show a homogenous reduction around 30%
(13/40) of perceived disability. The scores seem independent
from different diagnosis or single or combined treatment. So the
presence of Sysimbrium in the treatment seems the common
factor facilitating reduction of perceived disability.
Conclusion
Vocal tract pathologies must be treated following Evidence
Based Medicine protocols. But Biagi [13] pointed out that in some
cases Phytoterapy mantains a pivotal role in the modern EBM.
“Main peculiar features of medicinal plants may be compared to

[21,22].
So we conclude that, in diagnosed absence of major diseases,
when in a Patient the desired effect is simply prompt reduction
of perceived disability to reduce resulting handicap, if prescribed
under physician control and instrumental assessment, monitoring
subjective perception of symptoms, phytotherapy may show

Sisymbrium officinale (L.) Scop. is a wild common plant of the Brassicaceae family. It is known as “the singers’ plant” for its traditional use in treating aphonia and vocal disability. Despite its wide use in herbal preparations, the molecular mechanism of action of S. officinale extracts is not known. The plant is rich in glucosinolates and isothiocyanates, which are supposed to be its active compounds. Some members of this family, in particular allylisothiocyanate, are strong agonists of the transient receptor potential ankyrin 1 (TRPA1) channel, which is involved in the somatosensory perception of pungency as well as in the nociception pathway of inflammatory pain. This study aims to isolate the glucosinolates and isothiocianates from fresh S. officinale to identify the major components and test their activity in in vitro assays with a cloned TRPA1 channel. Samples of cultivated S. officinale have been extracted and the active compounds isolated by column chromatography, HPLC and PTLC. The main components glucoputranjivin, isopropylisothiocyanate and 2-buthylisothiocianate have been tested on TRPA1. The glucosinolates glucoputranjivin and sinigrin turned out to be inactive, while isopropylisothiocyanate and 2-buthylisothiocyanate are potent agonists of TRPA1, with an EC50 in the range of the high potency natural agonists identified so far for this somatosensory channel.

The effects of bioactive volatiles ITCs are thought to occur mainly locally in the upper airways and oropharyngeal cavity, i.e., in the nose, mouth, throat, larynx, and vocal cords [7]. Here, the pungency of ITCs, due to the interaction with TRPA1 ion channel, is perceived. ...

Sisymbrium officinale (L.) Scop. (hedge mustard) is a wild common plant of the Brassicaceae family. It is known as “the singers’ plant” for its traditional use in treating aphonia and vocal disability. The plant is rich in glucosinolates and isothiocyanates; the latter has been demonstrated to be a strong agonist in vitro of the Transient Receptor Potential Ankirine 1 (TRPA1) channel, which is involved in the somatosensory perception of pungency as well as in the nociception pathway of inflammatory pain. Volatile ITCs are released by the enzymatic or chemical hydrolysis of GLSs (glucosinolates) during sample crushing and/or by the mastication of fresh plant tissues when the plant is used as an ingredient. Some functional food and drink model preparations have been realised: honey enriched with seeds and flowers, infusions, cold drink (voice drink), artisanal beer, and a fermented tea (kombucha). Using SPME-GCMS chromatography, we analysed samples of the plant and of the food preparations adopting conditions that simulate the release of isothiocyanates (ITCs) during oral assumption. Two active compounds, iso-propylisothiocyanate and 2-butylisothiocyanate, have been assayed. The concentration of ITCs varies according to temperature, pH, grinding conditions, and different plant organs used. Kombucha-type fermentation seems to eliminate the ITCs, whereas they are retained in beer. The ITCs’ concentration is higher when entire seeds and flowers are used.

S. officinale is rich in sulfated compounds (particularly glucosinolates, isothiocyanates and sulfated lactones), to which its beneficial properties have been related. ...

Spontaneous edible plants have an old history of use in popular traditions all around the world, and the rediscovery of these species could also be useful for the search of new drugs. Chenopodium album L. (Amaranthaceae) and Sisymbrium officinale (L.) Scop. (Brassicaceae) are two annual plants traditionally used both as food and herbal remedies against inflammatory disorders. In this work, the potential anti-inflammatory and anti-arthritic activities of these plant species have been investigated, together with their antioxidant potential. The phytochemical composition was assessed as well by means of gas chromatography coupled to mass spectrometry (GC-MS) and high performance thin layer chromatography (HPTLC). The antioxidant properties were assessed using the DPPH and β-carotene bleaching test. The ability of extracts to protect against lipid peroxidation was also examined in rat-liver microsomal membranes. All the samples showed a preservation of antioxidant activity up to 60 min. A significant inhibitory activity on the production of the pro-inflammatory mediator nitric oxide was induced in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells by the dichloromethane fraction of C. album extract, with an IC50 value equal to 81.7 ± 0.9 μg/mL. The same sample showed also a concentration-dependent anti-denaturation effect on heat-treated bovine serum albumin (IC50 = 975.6 ± 5.5 μg/mL), even if the best in vitro anti-arthritic activity was observed for the dichloromethane fraction of S. officinale extract, with an IC50 value of 680.9 ± 13.2 μg/mL.
... On the other hand, it is also important to make people aware of the lack of consistent and solid scientific data concerning the use of SO in humans, thus keeping in mind a precautionary principle whenever assuming a plant derivative. Nonetheless, a study reported in a non-indexed journal showed that a brief treatment with SO was effective in reducing the perceived disability of a group of subjects with vocal tract diseases [7]. These preliminary results need further confirmation, and the study is not present in the international bank "Clinical Trials"; however, the scientific community is gaining more and more awareness of the importance of finding scientific and rational answers to the consolidated and popular use of many plants or plant derivatives. ...

Sisymbrium officinale (hedge mustard and formerly called Erysimum officinale) is a common plant in wild lands of Europe and Africa. It is also cultivated for its seeds and leaves to be used in salad or mustard. Sisymbrium officinale is useful not only in culinary preparations, but it also seems to possess interesting therapeutic properties, especially for throat diseases such as aphonia and hoarseness. For this reason, it is commonly called “herb of singers” (in Italian, “Erba dei cantanti”). Indeed a cup of Sisymbrium officinale infusion is frequently consumed by singers before artistic performance, even if its beneficial ability still needs to be scientifically demonstrated. Some preliminary data can be analyzed, but new efforts and resources should be devoted to study and investigate a plant with valuable therapeutic potential. This review summarizes the data available for Sisymbrium officinale.

Herbs have been used for voice care since ancient times and many herbal remedies are still in use in every geographical areas and cultures, both as traditional medicine and as sources of botanicals used in commercial products. Many of these plants are used as extracts and other phytopreparates, and a full phytochemical analysis is sometimes incomplete or lacking. The mechanisms of action of these botanicals include anti-bacterial, anti-inflammatory, mucolytic and other general activities; nevertheless, mechanisms that could be specifically referred to voice are often unknown, as well as the corresponding molecular targets and therefore a rational approach in the use of these remedies is hard to be applied by phoniatricians. To address this problem, we collected information on plants used for voice care from several different geographical areas, using both literature data and a pool of contributors from an international network of artistic phoniatrics and vocologists. The plants have been organized in a database (Herbs for Voice Database) and classified according to the natural compounds contained in them, their molecular targets and the pathologies they are recommended for. This first database contains 44 plants, 101 phytocompounds and 32 recognized molecular targets. The distribution of herbs and phytocompounds according to the botanical families, their known biological activity, traditional uses and molecular targets were analyzed. In particular, data analysis shows that the somatosensory and pain receptor Transient Receptor Potential Ankyrin 1 (TRPA1) ion channel is targeted by a large number of different phytochemicals contained in the herbs for voice, and could therefore be involved in a mechanism of action common to many plants.

Sisymbrium officinale (L.) Scop., commonly known as "hedge mustard" or "the singer's plant" is a wild plant common in Eurasian regions. Its cultivation is mainly dedicated to herboristic applications and it has only recently been introduced into Italy. The active botanicals in S. officinale are glucosinolates, generally estimated by using UV or high-performance liquid chromatography (HPLC). Using both techniques, we measured the total glucosinolates from S. officinale in different parts of the plant as roots, leaves, seeds, and flowers. A comparison was made for cultivated and wild samples, and for samples obtained with different pre-treatment and fresh, frozen, and dried storage conditions. Cultivated and wild plants have a comparable amount of total glucosinolates, while drying procedures can reduce the final glucosinolates content. The content in glucoputranjivin, which is the chemical marker for glucosinolates in S. officinale, has been determined using HPLC and a pure reference standard. Glucoputranjivin and two isothiocyanates from S. officinale have been submitted to in vitro assays with the platform of bitter taste receptors of the T2Rs family. The results show that glucoputranjivin is a selective agonist of receptor T2R16.

Sisymbrium officinale is a wild Brassicaceae species that is known for its use in the alleviation of vocal inflammatory states. Since this species is particularly rich in bioactive compounds, there is an interest for developing cultivation protocols to use this plant as a leafy vegetable harvested at the 13th BBCH growth stage. Two wild populations of S. officinale (L.) Scop., denominate MI (Milan) and BG (Bergamo), have been used, and three different levels of nutrients (g/m2) have been provided such as 13 N, 7 P2O5, 8 K2O (100%); 9 N, 5 P2O5, 5.5 K2O (70%); and 6.5 N, 3.5 P2O5, 4.0 K2O (50%). The effects of different fertilization levels were evaluated on the yield, leaf pigments (chlorophylls, carotenoids), nitrate concentration, sugars content, and on the antioxidant compounds such as anthocyanins, total phenols and glucosinolates (GLS). Plant stress monitoring was performed by measuring the chlorophyll a fluorescence. Results indicated that yield was not affected and ranged from 0.18 to 0.47 kg/m2, and differences were not statistically significant for chlorophylls, carotenoids, and total sugars content. Nitrate concentrations were higher in the BG wild population (4388.65 mg/kg FW) during the second cultivation cycle and lower (1947.21 mg/kg FW) in the same wild population during the first cultivation cycle, both at the 100% fertilization level. Total phenols and anthocyanins were higher in the highest fertilization rate in the MI wild population during the second cycle. The GLS were higher in the lowest fertilization rate in the BG wild population (19 µmol/g FW) grown at the fertilization level of the 50%, and significant differences were observed in the second cycle. In conclusion, the 50% fertilization level can be considered the most suitable for our experimental conditions.

The minimally processed industry is always looking for produce innovation that can satisfy consumer needs. Wild leafy vegetables can be a good source of bioactive compounds and can be attractive for the consumer in term of visual appearance and taste. In this work, Sisymbrium officinale (L.) Scop., commonly called hedge mustard, was grown in a greenhouse and evaluated as a potential leafy vegetable. Two wild populations, Milano (MI) and Bergamo (BG), were grown in peat substrate and harvested at the commercial stage for the minimally processing industry. Leaf pigments such as chlorophyll and carotenoids were determined as well as chlorophyll a fluorescence parameters. Total sugars, antioxidant compounds such as ascorbic acid, phenolic index, total phenols, anthocyanins, and nitrate were determined at harvest. Significant differences between wild populations were found in April with higher nitrate content in BG, 2865 mg/kg FW than in MI, 1770 mg/kg FW. The nitrate levels of S. officinale measured in the present study are significantly lower than the maximum NO₃ level allowed in other fresh leafy vegetables. Ascorbic acid measured in November was higher in MI compared BG with values of 54.4 versus 34.6 mg/100 g FW, respectively. The chlorophyll a fluorescence data showed that BG reached optimal leaf functionality faster than MI. Overall results indicated that Sisymbrium officinale (L.) Scop. can be suggested as a potential leafy vegetable for the minimally processed industry.

To date, no instruments exist to quantify the psychosocial consequences of voice disorders. The aim of the present investigation was the development of a statistically robust Voice Handicap Index (VHI). An 85-item version of this instrument was administered to 65 consecutive patients seen in the Voice Clinic at Henry Ford Hospital. The data were subjected to measures of internal consistency reliability and the initial 85-item version was reduced to a 30-item final version. This final version was administered to 63 consecutive patients on two occasions in an attempt to assess test-retest stability, which proved to be strong. The findings of the latter analysis demonstrated that a change between two administrations of 18 points represents a significant shift in psychosocial function.

Volatile compounds of hedge mustard (Sysimbrium officinale) have been investigated for the first time. Forthy-two compounds were identified after hydrodistillation (without or upon autolysis) after gas chromatography and gas chromatography/mass spectrometry analyses. In addition, after decoction and hydrolysis of O-glycosides, 18 volatile O-aglycones were identified. In general, the main volatiles found in hydrodistillates were: isopropyl isothiocyanate (27.6-48.9%), 2-methylpropanenitrile (0.5-18.8%), (Z)-hex-3-en-1-ol (0.5-18.0%), sec-butyl isothiocyanate (4.9-9.4%), (E)-hex-2-enal (3.5-8.6%), (Z)-hex-2-en-1-ol (0.3-8.4%), octanoic (0.5-8.6%) and dodecanoic acid (0-5.0%), 2-methylbutanenitrile (0-4.6%), dibutyl phthalate (0-4.5%), and ethyl linolenate (0-3.6%). The main volatile O-aglycones were: 2-phenylethyl alcohol (21.5%), 6,7-dehydro-7,8-dihydro-3-oxo-alpha-ionol (9.3%), eugenol (8.3%), benzyl alcohol (7.0%), ethyl vanillate (5.2%), 6-(tert-butyl)-5-methylphenol (5.1%), vanillin acetone (4.7%), ethyl 4-hydroxybenzoate (4.3%), and 2-hydroxy-beta-ionone (3.8%). All hydrodistillates exhibited great potential of antibacterial activity against five Gram-positive bacteria, nine ampicillin-resistant Gram-negative bacteria, and four fungi at a concentration of 500 microg/ml using the disc diffusion method.

Glucoputranjivin (1) and isopropyl isothiocyanate (2) were isolated from an aqueous dry extract of Sisymbrium officinale and were identified by spectroscopic analysis. The antimutagenic activity of these compounds was evaluated in a bacterial reverse mutation assay using E. coli WP2, WP2uvrA, and WP2uvrA/pKM101 strains, in comparison with the extract. In the absence of the exogenous metabolic activation system S9, the thio compounds exerted antimutagenic activity against the direct-acting mutagen methyl methanesulfonate, in all strains. In the presence of S9, both thio compounds were active against the indirect mutagens 2-aminoanthracene, in WP2uvrA, and 2-aminofluorene, in WP2. The antimutagenicity seems to be due to specific mechanisms, such as the induction of the adaptive response or the excision repair system. Conversely, the inhibition of the CYP450-mediated activation of mutagens was not supported by the present results. An antimutagenic effect was also observed for the S. officinale aqueous extract against the arylamines 2AA and 2AF, but not against MMS. These results suggest that both thio compounds are involved in the antimutagenicity of S. officinale. The antimutagenicity of glucosinolate 1 is reported for the first time.

The aerial parts of Sisymbrium officinale Scop. are commonly used to treat airway ailments, moreover in antiquity the herbal drug was reputed to possess anticancer properties. The results obtained in present work support the traditional use and the properties ascribed to Sisymbrium officinale. In order to give a scientific basis to the traditional uses of Sisymbrium officinale, this study was aimed to evaluate in vitro the myorelaxant activity, the antimicrobial properties and the antimutagenic effect of an aqueous dry extract of the aerial parts of the plant. A phytochemical characterization of the extract was also performed. The myorelaxant activity was studied against the contractions induced by carbachol, histamine and leukotriene C(4), in isolated guinea-pig trachea. The antimicrobial activity was tested against six bacteria and one yeast. The Ames test, performed by the preincubation method, was used to study the antimutagenic activity of the extract by its capability to inhibit the mutagenic effect of 2-nitrofluorene, sodium azide, methyl methanesulfonate and 2-aminoanthracene, in Salmonella typhimurium TA98, Salmonella typhimurium TA100 and Escherichia coli WP2uvrA strains. The chemical composition of the extract was analyzed by TLC and HPLC. Sisymbrium officinale showed to reduce the chemically-induced contractions of isolated guinea-pig trachea with major potency against leukotriene C(4) and histamine. The extract did not show any antibacterial activity. The Ames test showed a strong antimutagenic activity against 2-aminoanthracene, in Escherichia coli WP2uvrA and in Salmonella typhimurium TA98 strains. The phytochemical study highlighted the presence of putranjivine, the glucosinolate marker of Sisymbrium officinale, and of proline. The myorelaxant activity of Sisymbrium officinale offers a scientific basis to its use in traditional medicine. The strong antimutagenic effect suggests further studies to evaluate its possible chemopreventive activity.

The review discusses the large placebo effect associated with cough medicines and speculates on the observation that most cough medicines are formulated as sweet syrups rather than capsules or tablets. The review proposes that the major benefit of cough medicines for treatment of cough associated with common cold is related to the placebo effect rather than the pharmacological effect of an active ingredient. The placebo effect is discussed in terms of physiological effects of cough syrups associated with the taste of the medicine and true placebo effects associated with belief in the therapy. The idea is developed that a sweet taste may modulate cough at the level of the nucleus tractus solitarius, possibly by influencing the production of endogenous opioids.
