As per Siddha literary text, the non healing wounds are termed as Kaaliga viranam (காலிக விரணம்). Many effective treatments for the facilitation of wound healing is available in Siddha medicine of which Manjitti kudineer (மஞ்சிட்டி குடிநீர்) has been recently studied at National Institute of Siddha.
It has been observed that on administration of Manjitti kudineer along with usual wound hygiene causes the wound margins to shrink and close in a short span of 15-90 days regardless of the wound chronicity in the majority.
This formulation in particular serves as a powerful agent to contract the wound margins and eventually close to heal it. Even wounds of several years duration (i.e., 30 years) had been healed in 3 months time.
Various types of wounds caused due to venous (varicose) and arterial insufficiency, diabetes, trauma etc., respond well to the above Siddha treatment.
Wounds as big as 10cm dimension also get healed with this regimen of treatment. Study showed that the Manjitti Kudineer was effective in enhancing the Wound contraction and epithelialization.
