Discussion

In many classical literatures, there is no mention about Virya of Surana, while based on general principles of Dravyaguna, Acharya PV Sharma[18] mentions properties of Surana comprehensively and they are as follows. Rasa - Katu, Kashaya; Guna - Laghu, Ruksha, Tikshna; Virya - Ushna; Vipaka - Katu; Pravaba - Arshaghna; Karma - Ruchivardhak, Deepana, Pachana, Anulomaka, Shulaprasamak, Arshaghna, Krimighna, Sothahara; Rogaghnata - Aruchi, Agnimandya, Vivandha, Udarshula, Gulma, Yakrit - Pleeha Rogas, Arsha & Krimi. The properties mentioned in the classics can be correlated with certain modern parameters, which have been already researched are given below.

Effect of Surana in Aruchi & Agnimandya: In Ayurveda, "Aruchi" refers to a condition characterized by a loss of appetite or taste disturbances. Surana is having ‘Deepana’ & ‘Pachana’ properties. By Deepana, it stimulates the digestive fire (Agni) to enhance digestion, while by Pachana it aids in digesting and eliminating undigested food material (Ama) from the body, which can enhance appetite & metabolic functions.


By improving digestion and increasing appetite, Surana may help individuals suffering from Aruchi & Agnimandya.

Effect of Surana in Vivandha: Vivandha refers to constipation or obstructed defecation in Ayurveda. Surana is having ‘Anulomaka’ property by which Surana is traditionally used as a natural laxative in Ayurveda. It contains compounds that are believed to have a mild laxative effect, helping to soften stools and promote bowel movements. This property can be beneficial in relieving constipation and facilitating regular bowel movements in individuals experiencing Vivandha.

Surana as Arshaghna: In Ayurveda, Arsha is a lifestyle disorder caused due to- ‘Agnimandya’ which happens because of some important predisposing factors like- sedentary lifestyle, intake of fast food, lack of physical exercise & careless attitude towards responding to natural urges i.e. suppression & forceful creation of defecation, flatus etc. Surana having qualities like- ‘Deepana’, ‘Pachana’, & ‘Anulomaka’ have direct impact to balance Agni (Digestive fire). Almost each Samhitas & Nighantus have described that Surana is having ‘Arshaghna’ properties because of above said reason. In many recent researches, it is proved that - Tuber of Surana having curative action on hemorrhoids through anti-inflammatory and antioxidant properties. Sanjay Jain et al. were evaluated against ethanolic and aqueous extracts of Amorphophallus campanulatus (Roxb.) tubers carbon tetrachloride (CCl4) induced hepatic damage in rats. They extract at a dose of 500 mg/kg were administered orally once daily. This study suggests that possible mechanism of this activity may be due to free radical scavenging potential caused by the presence of flavonoids in the extracts.[19]

Effect of Surana in Yakrit-Pleeha Rogas: Surana is indicated in the treatment of Yakrit rogas (liver disorders) and Pleeha Rogas (spleen disorders) because of its Hepatoprotective Properties, Anti-inflammatory Effects, Immunomodulatory Effects, Detoxifying Effects. It is proved through various scientific researches & published studies. Hepatotoxicity was induced by CCL4. Ethanol and Aqueous extract show hepatoprotective effect at the dose 500mg/kg dose.[20] Macerated methanol extract also exhibits protective activity against Acetaminophen indued hepatotoxicity.[21]

When mice treated with tuber aqueous extract and methanol extract decrease in clearance index was observed to prove immunomodulatory effect. Spleen index and DMH (Dimethylhydrazine) response shown good result.[22]

Surana as Krimighna: Surana possesses a bitter and pungent taste. Bitter and pungent tastes are traditionally associated with anti-parasitic and purifying actions in Ayurveda. These tastes help in cleansing the body and expelling worms and parasites. & also, Surana has a heating potency (Ushna Virya). The heating nature of Surana helps in destroying parasites, as many parasites and worms thrive in a cooler environment. Surana is known for its effect to pacify Kapha and Vata Doshas. Parasites and worms are often associated with imbalances in these Doshas, particularly Kapha, which can create a conducive environment for their growth.

By balancing these Doshas, Surana helps in preventing and treating parasitic infestations. It is proved in recent researches that Chloroform extract, methanol extract, petroleum ether extract and isolated crude tannins were studied for anthelminthic activity. Anthelminthic activity of methanol extract of tubers shows prominent activity against Pheretima posthuma, Tubifex tubifex (a variety of worms) Death time and paralysis time of isolated crude tannins was very close to albendazole.[23]

Effect of Surana in Udarshula: In AyurvedaUdarshula’ refers to abdominal colic. In our classics, it has been mentioned that any type of pain (Ruja) occurs due to imbalance of Vata Dosha. Surana is particularly effective in balancing Vata and Kapha Doshas. Abdominal pain is often a result of Vata Dosha imbalance. By pacifying Vata and Kapha Doshas, Surana helps to reduce the symptoms associated with these imbalances, including pain. Further, the post-digestive effect of Surana is pungent (Katu Vipaka), which further aids in digestion and reduces gas and bloating, thereby alleviating pain. Some recent researches showed that Surana has been noted to have anti-inflammatory properties, which help in reducing inflammation in the gastrointestinal tract. This reduction in inflammation can significantly alleviate pain. Its analgesic properties contribute directly to pain relief by reducing the sensation of pain in the affected areas.


The corm of Amorphophallus species have diverse property of free radical scavenging, the methanolic and aqueous extract of Amorphophallus campanulatus tuber have shown good antioxidant activity.[24]

Analgesic activity in the whole plant of Amorphophallus campanulatus have shown effective analgesic activity using tail flick and tail immersion techniques by measuring the reaction time of the animals (rats). The extract showed reaction times of 7.33 (p<0.001) and 7.83 (p<0.001) min at a dose of 200 mg/ kg while the normal and reference groups exhibited reaction times of 2.16, 2.66 and 8.16 (p<0.001) and 8.5 (p<0.001) which supports the fact of its use in traditional medical practice.[25]

Conclusion

Surana is a commonly available vegetable with properties of Ruchivardhak, Deepana, Pachana, Anulomaka, Shulaprasamak, Arshaghna, Krimighna, Sothahara etc. This review comprehensively explores the therapeutic potential of Surana (Amorphophallus campanulatus), from both traditional Ayurvedic and modern scientific perspectives. The findings from this review highlight the significant medicinal value of Surana, validating its long-standing use in Ayurvedic medicine and its relevance in contemporary healthcare. Surana is recognized for its potent anthelmintic properties, effectively expelling intestinal parasites and promoting gut health.

The reason why Surana is so effective in treating hemorrhoids is because of its capacity to balance the doshas of Vata and Kapha, improve digestive fire, and have anti-inflammatory properties. Research supports the antimicrobial, anti-inflammatory, and analgesic properties of Surana, aligning with traditional Ayurvedic uses. Its nutritional profile, rich in fibre, vitamins, and minerals & amino acids, contributes to its role in promoting digestive health and preventing constipation. In India, Surana is added to many traditional recipes to improve the food as well as the health benefits. Its diverse medicinal properties make it a valuable herb for treating various health conditions, particularly those related to the digestive system. Integrating Surana into dietary practices and therapeutic regimens offers a natural and effective approach to enhancing overall health and well-being.
