Majja dhatu corresponds to the nervous system tissues—the brain, spinal cord, and nerves—and is tied to consciousness, sensation, and motor coordination. Because the brain is the central organ where nervous signals are processed and integrated, it is the primary site for Majja dhatu. The other options relate to different bodily systems—heart and lungs to circulatory/respiratory functions, and skin to the skin tissue—and do not represent nervous tissue in the context of Majja dhatu.

Long pepper brings heating, sharp, and penetrating action that stimulates digestion and movement. When a fermented preparation like Pippali Asava is used, these properties help counter both dryness and irregularity typical of Vata, and stagnation or mucus associated with Kapha. In a pattern where Vata and Kapha are involved, this combination of traits can restore balance by boosting metabolism, improving circulation, and reducing congestion. By contrast, a predominantly Pitta condition could be aggravated by the warmth, so it isn’t the preferred choice. Thus Pippali Asava is described for Vata–Kapha combinations.

Nashtartava is addressed in Ayurveda by strengthening and nourishing the reproductive tissues (artava dhatu) to help restore normal menstrual function. In this framework, Shatavari, Bala, and Kumari Asava are classic female-reproductive tonics. Shatavari is renowned for supporting female reproductive health—it's a gentle, nourishing herb that helps balance the systems involved in menstruation. Bala acts as a strong nourishing tonic that fortifies overall vitality and reinforces reproductive tissues, which can help when artava is weak or irregular. Kumari Asava, which centers on Aloe (kumari), combines herbs oriented toward supporting regular menstrual flow and the health of the reproductive system. Ginseng, while a well-known adaptogen in other traditions, is not a traditional Ayurvedic remedy listed for nashtartava. It isn’t part of the classical Ayurvedic formulations used to restore menstrual function, whereas the three herbs above are commonly cited for this purpose. So the herb that isn’t listed as helpful for nashtartava is Ginseng.

Grudrasi is understood as a vataja disorder that affects the nervous system, specifically the pathways along the sciatic nerve. When vata matures or vitiates and travels into the majja dhatu (nerve tissue), it lodges there and travels along the nerve channels to the sciatic nerve. This majja gata vata produces the characteristic radicular pain, numbness, and weakness down the leg that radiates along the sciatic nerve. So the samprapti centers on vata vitiation that has entered majja and localized to the sciatic nerve, causing the painful, neuropathic pattern seen in grudrasi. The other options describe dosha or tissue involvement in organs or systems not aligned with nerve-driven radicular pain, which is why they’re less appropriate.
