Infrequent use of medicinal plants from India in snakebite treatment

Abstract

Snakes have fascinated humankind for millennia. Snakebites are a serious medical, social, and economic problem that are experienced worldwide; however, they are most serious in tropical and subtropical countries. The reasons for this are 1) the presence of more species of the most dangerous snakes, 2) the inaccessibility of immediate medical treatment, and 3) poor health care. The goal of this study was to collect information concerning rare, less utilized, and less studied medicinal plants. More than 100 plants were found to have potential to be utilized as anti-snake venom across India. Data accumulated from a variety of literature sources revealed useful plant families, the parts of plants used, and how to utilize them. In India, there are over 520 plant species, belonging to approximately 122 families, which could be useful in the management of snakebites. This study was conducted to encourage researchers to create herbal antidotes, which will counteract snake venom. These may prove to be an inexpensive and easily assessable alternative, which would be of immense importance to society. Plants from families such as Acanthaceae, Arecaceae, Apocynaceae, Caesalpiniaceae, Asteraceae, Cucurbitaceae, Fabaceae, Euphorbiaceae, Lamiaceae, Rubiaceae, and Zingiberaceae are the most useful. In India, experts of folklore are using herbs either single or in combination with others.

1. Introduction

For centuries, plants have been important in the treatment of a wide variety of illnesses, diseases, and disorders.1, 2 The inherent traditional systems of medicine, along with information from conservative folklore, are serving a large section of the populace, particularly in rural and tribal areas, despite the dawn of modern medicine. Ethnobotany is the scientific and systematic study of traditional knowledge and customs of people concerning plants and their medical, religious, and other uses. Studies involve literature surveys, detailed investigations, analyses, interpretation, and conclusions concerning various research and scientific data. An ethno-medico-botanical appraisal includes discussions with natives, as well as utilization of available facts and data regarding folklore literature.³ Indigenous medicinal plant species have been added to several recent drug formulations and preparations for fundamental health care.³

2. Methodology

The current study provides a collection of information on medicinal plants that grow and can be utilized in various regions of India for snakebite treatment. The appropriate literature, including books, journals, and reports, was reviewed. The relevant information was searched using various electronic catalogs (e.g., Google Scholar, Medline, NISCAIR, Science Direct, Scirus, and Scopus) and keywords such as “anti-venom activity,” “ethno botany,” “ethno pharmacology,” “Indian,” “indigenous,” “medicinal plants,” “snake bite,” and “survey.” It was difficult to include all the information regarding medicinal plants used for snakebite treatment, and as such this study focused on information that would be easily accessible for researchers. Over the last few decades, people from different tribal communities have been recoding and maintaining data regarding traditional and tribal knowledge related to the use of medicinal plants. However, this information has, until now, not been made available to the modern world. In this regard, information on tribal and local use of various plants has been made available and a systematic “ready to use” list of medicinal plants has been formed. The list consists of data, including biological source(s), family, local name(s), part(s) used, method(s) of preparation/formulations, and reference(s). In this review, care was taken to ensure the identification of the herbal medicinal plants that were in the original resources (Table 1).

3. The Indian subcontinent and snakes

The Republic of India (3^rd largest country in Asia and 7^th by area in world) is a multilingual country home to a diverse culture with a rich and glorious heritage. India's land border covers 151,067 km, which is shared with neighboring countries, including Bangladesh (border shared = 40,967 km), China (3488 km), Pakistan (3323 km), Nepal (1751 km), Myanmar (1643 km), Bhutan (699 km), and Afghanistan (106 km). India's coastline covers 75,166 km, and land area including island territories covers more than 3,287,260 km². Some of these countries were part of India before the partition.⁴

India has numerous and diverse medico-herbal plants. They are dispersed, depending upon geographical and ecological conditions, across the country. Of these, more than 1500 species have demonstrated significant medicinal properties.⁴ Envenomation, especially by snakebite, is a serious worldwide public health crisis.5, 6, 7, 8 Inappropriate and unwarranted treatment results from reasons such as the failure to identify the snake species (venomous or non-venomous), which increases the risk of complications. According to the Integrated Taxonomic Information System (ITIS), Elapidae and Viperidae are the two major families of venomous snakes. Elapidae consists of 325 species distributed in 61 genera. Viperidae includes 224 species distributed in 22 genera. In and around India, approximately 216 species of snakes belong to these families, and only 52 are known to be poisonous.9, 10 The ‘Big Four’ snakes cause the largest number of snakebite deaths on the Indian subcontinent. The ‘Big Four’ snakes consist of Russell's viper (Daboia russelii; Marathi translation, ghonas tawarya), Indian cobra (Naja naja; Marathi translation, Nag), saw-scaled viper (Echis carinatus; Marathi translation, phoorsa), and common krait (Bungarus caeruleus; Marathi translation, manyar kanadar) (Fig. 1).¹¹ Apart from these big four, the hump-nosed viper is also hazardous.¹² Envenomation is a ‘choice’ and voluntary action or reaction by snakes. Their bite is a natural protective defense mechanism. All venomous snakes have the ability to bite without including venom (dry bite).¹³ Farmers, fieldsmen, and outdoor workers find suffering from snakebites to be an occupational hazard.¹⁴ It is also a leading problem in rural areas of India. It is estimated that snakebite poisoning causes approximately 50,000 deaths annually, and the number is likely higher because not all cases from rural areas are reported.10, 15

4. Snake venom and snake anti-venoms

Snake venom is one of the most intense and ‘mysterious’ biological fluids within the animal kingdom, causing complex medical effects. This is because of the presence of complex mixtures of proteins, peptides, and contain at least 25 enzymes.16, 17 Venom is a complicated combination of proteins (both enzymatic and non-enzymatic), peptides, and small organic compounds, such as acetylcholine citrate and nucleoside.18, 19 There are many potential effects of snake envenomation on humans; however, a few broad categories of major clinical significance are:

• 1.Systemic myolysis
• 2.Flaccid (drooping) paralysis
• 3.Coagulopathy and hemorrhage
• 4.Cardiotoxicity
• 5.Renal damage or failure
• 6.Local tissue injury at the bite site

Each of these may cause a number of secondary effects, and each is associated with potential morbidity and mortality.³ Similar to other modern medicines, anti-venom can have side effects. In addition, it takes too long to develop and is expensive. Strict and specific conditions are required for long-term storage.¹⁰ Because of the lack of availability of antidotes and anti-venoms at any specific time, alternatives from plant sources (which are abundant) should developed. Adequate information about herbal preparations or formulations is needed. The Indian system of medicine, especially Ayurveda medicine, has thrown light on this subject. A variety of plants mentioned in Ayurvedic literature are useful in snakebite treatment.²⁰ Considering that treatment at a proper clinic or hospital is at an unreachable distance for approximately 80% of victims, these people are primarily treated or handled by a traditional practitioner, or Vaidya, or other tribal herbalist. If the situation is beyond their control, they must proceed to a nearby clinic or hospital for advanced therapy.⁸ The traditional practitioners rely on various plants for treatment because they are knowledgeable about a variety of plant species that are helpful against snakebites and associated complications.3, 21 In the management of snakebites, there are two main aspects:

• 1.Proper first aid treatment and
• 2.Anti-venom/anti-ophidian treatment, such as serum therapy

Because of side effects or adverse events (e.g., anaphylactic reactions), serum sickness and sometimes the anti-venom itself produces complications during treatment.²²

5. Diversity of India

World Health Organization (WHO) stated that almost 80% of the population in developing countries depend on various herbal plants for the management of diverse diseases and illnesses because of the lack of modern health care services.3, 23 In addition, for prime health care, people are dependent on their earnings and improvement of the standard of living. More than 65,000 plant species are traditionally used in addition to modern medicines.²⁴ In India, Ayurveda is the most widely practiced system of medicine, which has a marvelous diversity of plant information. The Republic of India has 29 states and seven union territories comprising an area of 3,287,263 km². The Indian people speak a variety of languages, including 23 regional languages: Assamese, Bengali, Bodo, Dogri, Gujrathi, Kannada, Kashiri, Kokborok, Konkani, Maithili, Malayalam, Manipuri, Marathi, Mizo, Nepali, Odia, Punjabi, Sanskrit, Santali, Sindhi, Tamil, Telugu, and Urdu. Apart from these, other local or tribal people have their own tribal or native language per locality. India encompasses different ethnic groups with over 539 core indigenous people living in diverse territories. It has varied cultures, foods, traditions, and religious rituals, which causes separations among the people. Furthermore, there is a wealth of knowledge of conventional medicine, particularly herbal and folk medicine, for treatment of snakebites.

6. Clinical significance of snakebite

Traditional herbalists treat people earlier and use plants to cure various complications and ailments.³ The snake is still not perfectly understood to worldwide researchers. The word ‘snake’ invokes feelings of fear because of an instinctive human emotion and its image is powerful and primal. Snakes are as fascinating to psychologists, pharmacologists, and clinicians as they are to evolutionists. Snakes are either poisonous or nonpoisonous. Snakebites can be considered as environmental or occupational hazard because they occur regularly and repeatedly, with overwhelming frequency, particularly in remote rural areas in tropical developing nations. It is estimated that each year in India there are more than 80,000 snake envenoming and 11,000 deaths, which makes India a seriously affected nation. Snakes are present on each continent, except Antarctica.⁹ Mishal et al listed some critical and medically significant (clinical) conditions and syndromes related to snakebite envenomation¹⁴ as follows:

• 1.Local or restricted area envenoming (swelling of the affected part) with hemorrhage or difficulty clotting (this is particularly seen in Viperidae envenomation).
• 2.Local or restricted area envenoming (viz. swelling) with hemorrhage or difficulty clotting damages the kidneys or contributes to infections that cause neuro-paralysis and shock.
• 3.Local or restricted area envenoming (such as swelling) along with paralysis.
• 4.Paralysis with/without local or restricted area envenoming.
• 5.Paralysis with urine that is dark brown in color in addition to acute kidney injury.

7. Composition of snake venom

Medical science occasionally ignores community health values. Snake venom is rich in protein and peptide toxins. These proteins have a definite action on numerous tissue receptors. The wide range of action of snake venoms makes them clinically demanding and scientifically interesting, in particular, for drug design.²⁵ The mysterious biological nature of venom and its complex medical effects have long captured human imagination and inquisitiveness. Venoms, mainly snake venoms, have been the focus of ancient mythology, early biomedical speculation, folklore, and scientific investigation, in addition to pharmacognosy.²⁴ The venom of any species may have more than 100 diverse toxic and non-toxic proteins and peptides, along with non-protein toxins (amines, carbohydrates, lipids, and additional small molecules).²⁵ Proteins and peptides comprise approximately 90 ± 05% of the dry weight of venom. Supplementary components in the venom consist of carbohydrates, metallic cations, nucleosides, biogenic amines, and a small amount of free amino acids and lipids. The venom of snakes contains at least 25 enzymes, although no single snake venom has all of them. Enzymes are responsible for catalyzing numerous precise biochemical reactions that occur in living matter. They are the mediators upon which cellular metabolism depend. Among the available choices, the more important snake venom enzymes are as follows: 5′-nucleotidase, acetylcholinesterase, arginine ester hydrolase, collagenase, DNase, hyaluronidase, lactate dehydrogenase, l-amino acid oxidase, NAD nucleosidase, phosphodiesterase, phospholipase A₂ (A), phospholipase B, phospholipase C, phosphomonoesterase, proteolytic enzymes, RNase, and thrombin-like enzymes. All these enzymes are not present in all venoms. Among the peptides originating in snake venoms are pre-synaptic and postsynaptic neurotoxins, myotoxins, cytotoxins, cardiotoxins, and potassium channel-binding neurotoxins, along with platelet aggregation inhibitors (disinterring).3, 26, 27

8. Snakebite treatment in India

Because India is the only country of its kind in terms of the diversity of geographical, environmental, and climatic features, it has a rich and wide-ranging flora of medicinal herbal plants that have been used since the Vedic period. A huge portion of the nation still uses plants as home remedies in rural and remote areas for a number of illness, infections, and diseases, including snakebites. India is a nation with mega diversity; moreover, approximately 10% of world's species are indigenous to India. Because India has a prosperous, flourishing, enlightening legacy, almost all Indians have directly and indirectly been connected with a variety of herbs during their ritualistic ceremonies and various cultural activities. A recent study found that rich ethno-medicinal knowledge could be gathered from the community members, which would provide a great advantage to future generations by documenting and preserving the knowledge. This requires that the ethno-medicinal plants used by the native tribal people should be comprehensively revised and the proper significance of these plant species assigned, such that they can be managed and conserved for the welfare of mankind.³ Reliable progress has been made in that direction. Snakebite treatment in India (before partition) consisted of various snake antivenom drugs and/or combination formulations, such as Surucuina (1908), Ofidina (1909), Viborina (1910), an unknown plant used by the Civil Surgeon of Hugli (1912), an ointment made by Mr M Robert of Bordeaux (1914), Goor Boinchee Antitoxicum (1915), Tiriyaq (1916, repeated in 1929), white champa pod and root (1920), Payam-i-Hayat (February 14, 1921), El Elixir Antiviperino Lexin (1923), remedy by firozuddin (June 1928), and lobelin (1929) that have been tested since 1908 in various pharmacological labs across India, then British India and the Indian subcontinent.²⁸ The severity of snakebite poisoning is always a catastrophic issue for the sufferer and physician. Usually death will result because of many reasons, such as failure of the patient to reach the hospital, lack of appropriate treatment, difficulty in production, deployment, and accessibility of current snake anti-venoms. The mortality rate depends largely on the species of snake. Elapid poisoning (viz. cobra and krait) always has a higher mortality rate than that of Viperidae poisoning (saw-scaled viper and Russell's viper). The point to be considered is that an approximately 70-kg healthy person will succumb to only a small quantity of venom, and typically it takes the venom 6 seconds or less to reach the heart.¹⁴ In various ancient texts and literature, more than 320 medicinal plants and more than 180 different combinations are reported to have snake anti-venom activity. However, after comprehensive evaluation, all of these Ayurvedic preparations from medicinal plants had no snake anti-venom properties.²⁸

9. Vaidya – Indian herbalist, physician, compounder and dispenser

In the Indian system of medicine, the Vaidya is known as doctor of herbs, who makes a diagnosis of illness and compounds medicinal preparations, such as asava, aristha, churna (powders), lotions, liniments, pills, syrup, and taila. Furthermore, many old-aged persons (such as a grandmother) are familiar with the application of various herbs. Practitioners of Ayurveda believe that every plant on the Earth has some significant medicinal property for the purpose of the good of the world; the right person just has to show you. The practitioner of Ayurveda states (Naasti Moolam Anaushadhim translation Every plant on earth has a medicinal property). Allopathy (the treatment of disease by conventional means, that is, with drugs having effects opposite to the symptoms) or modern medicinal systems sometimes has a number of undesired effects from drugs, such as adverse drugs reactions. Therefore, an increasing number of people in developed and developing countries are using medicinal plants for some betterment.³ The formulations or plant preparations rely on the availability of the plant part(s). Usually preparation is made by crushing the plant or its part(s) by using stones or pieces of wood. Often a juice or paste is made to apply to the affected area or sometimes is given orally. A number of villagers or Vaidya have a specific stone set called a “Paata-Varvantaa” (Fig. 2). The Paata is a Marathi language word meaning base on which the plant or its part(s) are kept. The Varvantaa is a Marathi language word meaning a pastel-like stone to crush the plants or its part(s). The present review is an attempt to cover the traditional/ethnobotanical medicinal plants utilized in various parts of India for snakebites. Apart from previous reviews, this will also help future researchers to recognize the herbal approach for the treatment of snakebites. In Table 1, the data from the current analysis is presented. Arrangement of medicinal plant species is in alphabetical order.

10. Conclusion

Mother Nature has given humans a most precious gift in medicinal plants. The natives of India are people who are very connected to Nature, as Indians are “celebration affectionate” people. In almost every festival in India, there is connectivity of human beings to animals and Mother Nature. The local tribes understand biodiversity and serve as a source of knowledge regarding proper use of medicinal plants. For various reasons, the focus altered from modern medicine to Ayurveda herbs and medicinal plants for various diseases or disorders. India is homeland for such a marvelous variety of diversity. In cultural heritage, India has a long history of medicinal plant utilization. This review has attempted to cover remarkable similarities among medicinal plants that are used across India. In our study, a total of 523 plant species belonging to 122 families were reported for treatment of snakebites. Furthermore, this review encompasses some plants that are rarely or less often used. The most common families include Acanthaceae, Apocynaceae, Arecaceae, Asteraceae, Caesalpiniaceae, Cucurbitaceae, Euphorbiaceae, Fabaceae, Lamiaceae, Rubiaceae, and Zingiberaceae (Fig. 3). For a long time, the traditional healers have practiced using herbal traditional medications for snakebite treatment, as well as numerous other diseases. Biological source(s), family, local name(s), part(s) used (Fig. 4), method of preparation, and reference(s) are provided to increase the ease of availability for the data.

There is a lot of information yet to be gathered and formulated. Ethno-botanical investigation is the future branch that will aid in maintaining good health for all mankind because much is still hidden and there are chances to make new phytochemical phytopharmacological drug discoveries, which will become the most reliable progression in the direction of utilization of medicinal plants for the treatment of various illnesses.
