Introduction to Ayurvedic Blood Purification

Ayurveda, often referred to as the “science of life,” is an ancient holistic healing system that originated in India over 5,000 years ago. Rooted in the intricate balance of mind, body, and spirit, it emphasizes prevention, wellness, and the harmonization of the individual’s constitution with the rhythms of the natural world. Among the vast treasury of Ayurvedic knowledge lies the concept of “blood purification,” a therapeutic approach designed to cleanse and rejuvenate the circulatory system.

Blood purification in Ayurveda is not merely about detoxifying the physical component of blood. It intertwines with the notion of eliminating ‘ama’ (toxic byproducts) and balancing the three doshas – Vata, Pitta, and Kapha – which are fundamental energies that govern physiological and psychological processes in the body. An imbalance in these doshas, combined with external environmental factors and dietary habits, can lead to the accumulation of toxins, manifesting in various ailments and a general feeling of malaise.

The Ayurvedic approach to blood purification incorporates a combination of dietary guidelines, herbal remedies, and detoxification treatments, tailored to an individual’s unique constitution. By enhancing the body’s natural detoxification processes, Ayurveda aims to restore optimal health, boost immunity, and ensure the smooth functioning of all physiological processes.

This journey into Ayurvedic blood purification will unfold the age-old wisdom of sages and provide insights into techniques that have been practiced and refined over millennia. Whether you’re a seeker of holistic wellness or simply curious about alternative medicinal practices, understanding the Ayurvedic perspective on blood purification promises to be both enlightening and transformative.

What is Blood Purification?

The Conventional View

In the medical world, blood purification often refers to procedures like dialysis or chelation therapy. These treatments aim to remove waste products and toxins from the blood.

The Ayurvedic Perspective

But Ayurveda takes a different angle. In Ayurveda, the idea is to cleanse the blood naturally through diet, herbs, and treatments to promote overall well-being. Intriguing, isn’t it? Acharya Sushruta explains in detail how blood can get vitiated and produce diseases. Blood or rakta dhatu has the ability to get vitiated by its own causes and can cause rakta dushti.

Why blood purification is important in Ayurveda?

When other ayurvedic treatments fail or if the patient is not responding then one must do purification of blood. In general, diseases caused by the vitation of blood do not respond to conventional ayurvedic treatments. Blood purification is a must to treat the diseases that are caused by blood vitaiation.

Understanding Rakta in Ayurvedic Way

The word Raktha is derived from the ‘Ranj dhatu’ that imparts the color. Raktha dhatu (blood and its components) is one of the seven dhatu told in Ayurvedic science. It is formed from the previous rasa dhatu.

Rasa dhatu comes in contact with Ranjaka pitta (one of the five types of pitta) in yakrut (liver) and pleeha (spleen) and attains the color to form raktha dhatu. Thus, the essence of rasa dhatu is the raktha dhatu.

Shonitha (red color), rudhira (to withhold), lohitha (that which heals), asruk (which gushes in the vessels), kshtataja (born out of trauma) are various synonyms of raktha dhatu. Raktha sustains life, provides strength, and complexion, and nourishes the subsequent mamsa dhatu. Some Acharyas consider raktha as a dosha also.

Diseases caused by vitiated/impure blood(Raktha pradoshaja vikara or dosha of raktha)

Raktha dosha here refers to raktha pradoshaja vikara (raktha becomes extremely vitiated by dosha). Raktha pradoshaja vikara are explained by various Acharya and vary from each other and the names are mentioned below:

  • Bleeding disorders (raktapitta)
  • Disease due to vata and rakta (vatarakta)
  • Herpes (visarpa)
  • Intoxication(made), Syncope (moorcha), coma (sanyasa)
  • Skin diseases(kushtha)
  • Obstinate urinary disorders including diabetes(prameha)
  • Obstinate urinary disorders (raktameha)
  • Micro-organisms originating in blood (shonitajaKrimi)
  • Abdominal lump due to blood (raktagulma)
  • Diarrhoea with blood (raktatisara)
  • Abscess with blood (raktavidradhi)

What causes blood vitiation?

The etiology mentioned for raktha pradoshaja vikara are – excess intake of katu (pungent), amla (sour)food, lavana (salt), kulattha (horse gram), dadhi (curds), masha (black gram), tila taila (sesame oil), madya (alcohol), anupa mamsa (meat of aquatic animals), viruddha aahara (incompatible foods), adhyashana (excess eating), ajeernashana (having food without digestion of the previous food), divaswapna (day time sleeping), vegavarodha (suppression of natural urges), krodha (anger), atapasevana (excess exposure to sunlight), abhighata (trauma).

How purification of blood is done?

Rakthamokshana is the procedure in Ayurveda to purify the blood. The word Rakthamokshana has two words – Raktha is blood and mokshana is to leave, so, to let the blood out is rakthamokshana. Sushrutha mentions this procedure as one among five purificatory procedures. The therapy is done to expel the vitiated blood and reduce the toxic substances preventing various raktha pradosha vikara (blood-borne diseases).

Rakthamokshana is divided into three types:

  1. Shastra vidhi
  2. Anu shastra vidhi
  3. Ashastra vidhi

Shastra vidhi karma: The instruments used are sharp. Prachchanna and Siravyadhana are the shastra vidhi karma.

Anu shastra vidhi: The instruments are blunt. Shringa and Alabu are the anu shastra vidhi karma

Ashastra vidhi: Jalauka or leech therapy.

Prachchanna karma: A sharp instrument is used to do bloodletting therapy.

  1. This is done if the raktha is ekadoshitha and pinditha (involving one dosha and is clotted).
  2. If the raktha dushti is twachasthitha (just beneath the skin)
  3. Asukumara – patients who are tolerable to the procedure

Siravyadhana karma: A sharp needle is used to puncture the vein.

  • Done if the raktha is sarvanga doshitha
  • Asukumara – patients who are tolerable to the procedure

Herbs that help in blood purification

Here are some Ayurvedic herbs believed to help in blood purification:

  1. Neem (Azadirachta indica): Neem is renowned for its detoxifying and blood-purifying properties. It’s often recommended for skin disorders due to its anti-inflammatory and antimicrobial properties.
  2. Manjistha (Rubia cordifolia): Manjistha is a popular herb known for its ability to purify and detoxify the blood. It’s often used to treat skin conditions like acne and eczema.
  3. Triphala: A combination of three fruits – Amalaki (Emblica officinalis), Haritaki (Terminalia chebula), and Bibhitaki (Terminalia bellirica) – Triphala is a powerful antioxidant and is considered an effective detoxifier.
  4. Guduchi (Tinospora cordifolia): Guduchi is known for its rejuvenating properties and its ability to boost the immune system. It also helps in detoxifying the blood.
  5. Burdock Root (Arctium lappa): Although not originally from the Ayurvedic tradition, burdock root is sometimes incorporated due to its potent blood-purifying capabilities.
  6. Turmeric (Curcuma longa): Known for its anti-inflammatory, antioxidant, and healing properties, turmeric is also considered beneficial for blood purification.
  7. Sariva (Hemidesmus indicus): Sariva is another herb known for its cooling and blood-purifying properties. It’s beneficial for skin-related issues.

Bloodletting therapy is one of the purificatory procedures and it helps in removing the impure blood from the body. Selection of the patient, time period, dosha involved, and type of procedure are to be considered during the therapy. Being a para-surgical therapy it can prevent many of the diseases. Hence, Rakthamokshana is both a preventive and curative therapy.
