The word 'Rakta' refers to red color. Thus Rakta dhatu literally means the body tissue that is red in color. Rakta dhatu is thus similar to blood tissue which is red in color. It is second in order of 7 dhatus forming building blocks of physical body. In Ayurveda, in the context of feminine health, the word 'Rakta' is also used to denote 'menstrual blood' or even 'ovum'.

+{{ToBeEdited}}{{NeedCitation}}The word 'Rakta' (रक्तम्) refers to the color 'Red'. Thus Rakta dhatu literally means the body tissue which is red in color. Therefore, rakta dhatu in Ayurveda is to some extent similar to blood tissue described in western medicine. It is second in order of 7 [[Dhatus (धातवः)|dhatus]] (धातु) forming building blocks of physical body. In Ayurveda, in the context of feminine health, the word 'Rakta' is also used to denote 'menstrual blood'.

+In Ayurveda Rakta dhatu has been referred by using various other terms like Shonita (शोणितम्), rudhira (रुधिरम्), asrik (असृक्), astra (अस्र), lohita (लोहितम्), kshataja (क्षतजम्).
 == Formation of Rakta dhatu ==
-The second portion called ‘poshaka rasa’ is carried forward to nourish the next dhatu i.e.rakta. [Cha.Sa. Chikitsa Sthana 15/16]
+Rakta dhatu is formed from '[[Rasa Dhatu (रस धातु)|Rasa]] dhatu'(रस धातु). When Rasa dhatu is subjected to the process of micro-transformation (सूक्ष्मपचनम्), one processed part of it is specifically utilized to provide nourishment to the next dhatu in order i.e. Rakta Dhatu (रक्त धातु). This part is responsible for development and nourishment of rakta dhatu in body.<ref>Charaka Samhita (Chikitsasthanam Adhyaya 15 Sutra 16)</ref> Transformation of this part of rasa into rakta happens by the action of ranjaka pitta (रंजक पित्तम् | one of the 5 types of Pitta dosha) at sites yakrut (यकृत्) and pliha (प्लीहा). <ref>Sushruta Samhita (Sutrasthanam Adhyaya 14 Sutra 4)</ref>
 == Location of Rakta dhatu ==
-Yakrut  and pliha are the chief sites of raktavaha srotas. Rakta is metabolized at these sites mainly. Also it flows through siras and reaches to every part of the body.
+Rakta dhatu is present everywhere in the [[Sharira (शरीरम्)|shariram]] (शरीरम्). However, the channel through which it is predominantly circulated and transformed is called as Raktavaha srotas (रक्तवह स्रोतसम्). Yakrut (यकृत्) and pliha (प्लीहा) are the chief sites of raktavaha srotas. Rakta is metabolized at these sites mainly. Also it flows through siras (सिरा) and reaches to every part of the body.
 == Panchabhoutik constitution ==
-The Rakta dhatu is constituted with the dominance of agni mahabhuta and all other mahabhuta. It possesses properties like peculiar smell (vistrata), liquidity(dravata), red color(raga), pulsation(spandanam) and lightness to get circulated (laghuta) due to Prithvi,jala,teja, vayu and akasha mahabhuta are spectively. [Su.Sa. Sutra Sthana 14/9]
+The Rakta dhatu which is red in color and serves as the seat of pitta dosha naturally shows dominance of agni mahabhuta. But Ayurveda acharyas have opined, after keenly observing its functions and nature that it shows signs of presence of every mahabhuta equally at the same time. To explain this, qualities of Rakta dhatu and their asssociation with each of the 5 elements has been narrated. See table 1. <ref>Sushruta Samhita (Sutrasthanam Adhyaya 14 Sutra 9)</ref>
-Rakta dhatu is neither too hot nor too cold(anushna-sheeta), sweet (madhura), unctuous (snigdha), red(rakta), heavy(guru), with peculiar smell (vistra).It can get affected by the same substances that provoke pitta dosha.[Su. Sa. Sutra Sthana 21/17]
