Natural drugs, especially of plant origin, are expected to play a major role in the healthcare programme in the 21st Century, a leading scientist has said.

“The revival of interest in plant-based drugs and other herbal products is mainly because of the widespread belief that ‘green medicine’ is healthier than the synthetic products,” said veteran scientist P Pushpangadan in a paper titled ‘Health Food and Nutraceuticals – Traditional Wisdom’.

“This is mainly due to the increasing evidences of the health hazards associated with the harmful side effects of many synthetic drugs and the indiscriminate use of modern medicines such as antibiotics, steroids,” said the paper, which will be presented at the ongoing Annam – National Food and Agro-biodiversity festival on Monday.

Pushpangadan is the director general of Amity Institute for Herbal and Biotech Products Development, and has previously served as director of the National Botanical Research Institute till 2006.

The preference for green food and medicine has resulted in the rapid growth of plant-based drugs, pharmaceuticals, nutraceuticals, functional foods and even cosmaceuticals.

The scientist said in the 1980s, this led to the rapid spurt of demand for health products such as herbal tea, ginseng and products of traditional medicine.

Health improvement and disease preventive strategies in treatment, prevalent in oriental systems, especially Indian (Ayurveda, Siddha, Unani and Amchi) and the Chinese systems of medicine are finding increasing acceptance all over the world.

“Because of this sweeping ‘green wave’ a large number of herbal drugs and plant-derived herbal products are sold in the health food shops all over the developed countries. According to some healthcare experts, there will be more dieticians rather than physicians in coming years,” Pushpangadan said.

How Green is This Medicine?

Ayurveda, the oldest health system in the world, is going in for a makeover, but is it all for the good? Till now, the biggest innovation had been coloured ayurvedic pills and capsules. But the government’s recent amendment of the 63-year-old Drugs and Cosmetics Act appears to allow a more fundamental change — ayurvedic medicine can now contain anti-oxidants, flavouring agents, preservatives and sweeteners. So is ayurveda about to lose its unique organic wholesomeness?

click & see the pictures…....(1)..…..(2)……………..

Ayurveda practitioners and drug-makers don’t think so. They say the additives, natural or synthetic, must be in permissible quantities in order that the medicine retains its natural properties. “The purpose of allowing the use of anti-oxidants or sweeteners is to increase the shelf life of the ayurvedic medicines,” says Dr S K Sharma, advisor to the Department of Ayurveda, Yoga & Naturopathy, Unani, Siddha and Homoeopathy (AYUSH). The reasoning is that once they last longer, it would be easier to market ayurvedic medicines nationally and internationally.

But Sharma cautions that the changed law is not “purely for commercial reasons. There is a strong need for scientific innovation. It’s time that we tried to improve ayurvedic medicines.” So, the anti-oxidants that are being allowed to use will prevent the medicine from decomposing. The additives, says Sharma, will only help in making ayurvedic medicines more stable than ever before.

Some ayurvedic practitioners admit that there are legitimate concerns about additives. Dr V V Doiphode, dean of Pune University‘s Department of Ayurveda, stresses the importance of testing any product before it is added to an ayurvedic drug. “The onus is on the drug-makers to ensure these (additives) aren’t detrimental to health,” he says. For that they will have to conduct extensive research and lab testing.

There are other ways of ensuring compliance, not least guidelines issued by the Indian Pharmacopoeia Commission (IPC), an autonomous institution under the Ministry of Health & Family Welfare. The IPC sets strict standards for drugs and other pharmaceutical products. Add to this, the wording of the amended Drugs and Cosmetics Act, which allows “only natural colouring agents as permitted under rule 26 of Prevention of Food Adulteration Rules 1955 for ayurveda, siddha and unani drugs.”

But what if someone wanted to market a flavoured chyawanprash, say chocolate, to attract the international market? Would that be more synthetic than traditional chyawanprash? Not really, so long as it retains its original properties, says Ranjit Puranik, CEO of Shree Dootapapeshwar Ltd, ayurvedic drug-maker and exporter.

The loophole, however, is that a product like chyawanprash, which is made of 54 herbs — of which amla (gooseberry) is the main — can be marketed internationally as a dietary supplement rather than a medicine. If it has to be marketed as a medicine, then all the 54 herbs have to go through a standardisation process that will certify that none of the herbs are harmful to health.

The amended act allows synthetic additives in ayurvedic drugs but insists they “carry a statutory warning stating the name and quantity of the artificial sweetener.” Puranik says it’s up to the individual manufacturer to decide how natural he wants the ayurvedic drug to be. And if he uses a large quantity of synthetic additive “he clearly can’t then sell the product as ayurveda”.

That may affect ayurvedic core market, but the holistic health treatment has a long way to go in persuading India and the wider world of the goodness of its old-style organic approach to healing. Industry experts estimate that the global market for ayurveda is worth $120 billion. But India’s ayurveda exports are a paltry Rs 450 crore or $91 million. China and Sri Lanka lead the world in ayurveda manufacture and export.

India is finally trying to close the gap by adding innovation to the ayurveda mix. “These medicines can be tweaked a bit to suit people’s tastes, but the medicinal properties should be maintained. Say for instance, a popular ayurvedic medicine, kashayam, is now available in the form of capsules and tablets. This has been achieved by spray drying but the original properties are not tinkered with.” says V G Udayakumar, president of the Kerala-based Ayurveda Medical Association of India. He believes the same can be applicable to other medicines too.

But there’s some way to go before the humble hajmola becomes the world’s prescribed cure for indigestion.

India To Boost Tribal ‘Folk Medicine’

India will document, validate and popularise folk medicine practices of tribals across the country and even start institutes for their study to save these traditions from extinction.

“Folk medicine is different from ayurveda, homeopathy or unani. These are local medicinal procedures practised by tribals across India. We are trying to document, digitise and scientifically validate them,” said Verghese Samuel, joint secretary, Ministry of Health and Family Welfare.

“Due to modern systems of medicine, this health heritage is losing its popularity. We are trying to save these good practices through the initiative,” Samuel said.

Sanjeev K. Chadha, director, department of AYUSH (Ayurveda, Yoga and Naturopathy, Unani, Sidha and Homeopathy) in the ministry, said: “Because of folk medicine practices, tribals in India have a very good immune system. If they are getting benefits out of these practices then there must be something good about these practices.

“These age-old traditions should not be lost in the wilderness. We will do research on these practices and record them. All the good practices would also be considered from patenting.”

There are over 130 tribal groups in India, many from north eastern states.

Chadha said the health ministry had decided to establish a North Eastern Institute of Folk Medicine at Pasighat, Arunachal Pradesh. The state government has already given over 40 acres of land for the purpose and the institute will come up at a cost of nearly 330 million.

“The institute will dedicate itself to the cause. Research and scientific validations will also be done there. The institute may soon have branches in states like Orissa, Jharkhand and Chhattisgarh among others.”

Talking about the institute’s location, he said north eastern states were full of folk medicinal practices. “From malaria, to diarrhoea to wounds, people in this region use folk medicines and it’s better to start from there.”

Chadha said folk medicine was “a pool of knowledge” that had to be tapped.

“The practices are very utilitarian. We as a nation with diverse culture can’t allow a body of knowledge to perish. Like manuscripts, here is a pool of knowledge that needs to be tapped for a greater cause, for betterment of millions of people.

“Who knows it may give India a different pedestal in the health community of the world.”
