1. Definition of Dūṣya
In Ayurvedic pathology, Dūṣya (दूष्य) refers to those body components—namely dhātus (tissues) and malas (wastes)—that become “spoiled,” “polluted,” or “vitiated” when doṣas (Vāta, Pitta, Kapha) turn abnormal and combine with them. Under normal conditions, doṣa, dhātu, and mala work in harmony to sustain health. However, once doṣas become aggravated and enter various tissues or waste channels, they distort or contaminate these structures. This process is the hallmark of dūṣya duṣṭi (vitiation of the substrates).
Key Point:
- Dhātus and malas are the recipients of pathological impact.
- When doṣas infiltrate dhātus/malas, they transform these components into dūṣyas, thereby completing the disease complex.
Clinical Insight:
Recognizing which dhātu or mala is primarily “spoiled” by vitiated doṣas is crucial for accurate diagnosis and targeted treatment. For instance, if aggravated Pitta lodges in the Rakta dhātu, the disease will present predominantly with blood-related symptoms such as bleeding tendencies or inflammatory lesions in the skin.
2. Enlistment of Dūṣyas
Classical Ayurvedic texts commonly enumerate ten dūṣyas:
- Rasa (plasma/lymph)
- Rakta (blood)
- Māṃsa (muscle)
- Meda (adipose/fat)
- Asthi (bone)
- Majjā (bone marrow / nerve tissue)
- Śukra (reproductive tissue)
- Purīṣa (feces)
- Mūtra (urine)
- Sveda (sweat)
Of these, the first seven (Rasa through Śukra) are dhātus, while the last three (Purīṣa, Mūtra, Sveda) are malas—excretory products crucial for bodily homeostasis.
3. Specific Features of Dhātu Vṛddhi and Kṣaya
Each dhātu can undergo vṛddhi (increase) or kṣaya (decrease) based on dietary, lifestyle, or pathological factors. The Suśruta Saṃhitā (mainly Chapter 15) describes classical signs indicating whether a dhātu is in an excessive or deficient state. Recognizing these patterns helps in pinpointing which tissue is imbalanced and informs suitable treatments, such as nutritional support for kṣaya or metabolic reduction for vṛddhi.
3.1 Rasa Dhātu
a) Rasa Vṛddhi (Excess)
“रसोऽतिवृद्धो हृदयोत्क्लेदं प्रसेकं चापादयति।”

4. Specific Features of Mala Vṛddhi and Kṣaya
Ayurveda identifies Purīṣa (feces), Mūtra (urine), and Sveda (sweat) as the primary excretory products (malas). When doṣic aggravations impact these waste channels, they can be overproduced (vṛddhi) or underproduced (kṣaya), each leading to distinct clinical pictures.
4.1 Mūtra (Urine)
a) Mūtra Vṛddhi (Excess)
“मूत्रं मूत्रवृद्धिं मुहुरमुहुः प्रवृत्तिं बस्तितोदमाध्मानं च।”

- Muhur-muhuḥ pravṛtti: Frequent urination in short intervals.
- Basti-toda, ādhmāna: Bladder pain or distension.
Clinical Insight:
Resembles conditions like diabetes mellitus (prameha) or overactive bladder syndrome, with recurring urges and possible lower abdominal discomfort.
b) Mūtra Kṣaya (Deficit)
“मूत्रक्षये बस्तितोदोऽल्पमूत्रता च।”
(S.Su. 15/11)
- Alpa-mūtrata: Reduced urine output (oliguria).

4.2 Purīṣa (Feces)
a) Purīṣa Vṛddhi (Excess)
“पुरीषमाटोपं कुक्षौ शूलं च।”
(S.Su. 15/15)
- Āṭopa: Gurgling, bloating, or gaseous distention in the abdomen.
- Kukṣi-śūla: Abdominal pain or heaviness.
- Frequency or quantity of stool may increase (loose or bulky motions).
Clinical Insight:
This state can manifest as diarrhea, incomplete evacuation but frequent urges, or IBS-like patterns with gassy discomfort.
b) Purīṣa Kṣaya (Deficit)
“पुरीषक्षये हृदयपाश्वर्पीडा सशब्दस्य च वायोरूध्वर्गमनं कुक्षौ सञ्चरणं च।”
(S.Su. 15/11)
- Alpa-purīṣa: Decreased stool quantity.

Clinical Insight:
Likely indicates constipation, dryness in the colon, or insufficient fecal matter formation—leading to abdominal discomfort, bloating, or colicky pains.
4.3 Sveda (Sweat)
Though not elaborately covered in the same Suśruta references, Ayurveda broadly recognizes:
- Sveda Vṛddhi: Excessive sweating, often malodorous; can accompany hyperhidrosis or certain metabolic disorders.
- Sveda Kṣaya: Reduced sweating, dry skin, difficulty regulating temperature—sometimes seen in advanced dryness or certain neurological conditions.
5. Conclusion
- Dūṣya
- The dhātus (Rasa to Śukra) and malas (Purīṣa, Mūtra, Sveda) act as substrates that become contaminated by doṣic aggravations, thus labeled “dūṣya.”
- This contamination signifies deeper progression in disease, moving beyond mere doṣa imbalance to structural or excretory compromise.
- Dhātu Vṛddhi–Kṣaya
- Each tissue exhibits unique signs of excess (vṛddhi) or deficiency (kṣaya).
- Vṛddhi often manifests as heaviness, overgrowth, or hypertrophy, while kṣaya features dryness, weakness, and reduced functionality.
- Mala Vṛddhi–Kṣaya
- For urine and feces, excessive or insufficient outputs yield characteristic issues in elimination.
- Recognizing these patterns helps in understanding excretory disorders like diarrhea, constipation, polyuria, or oliguria.
- Importance in Diagnosis & Treatment
- Identifying which dhātu or mala is primarily vitiated shapes the treatment plan, whether it’s nourishing a deficient tissue, reducing an excessive one, or regulating excretions.
- Ayurvedic strategies include appropriate diet, herbal formulations, and panchakarma procedures to restore equilibrium at the tissue/waste level.
Takeaway:
By methodically checking signs of vṛddhi and kṣaya in each dhātu and mala, Ayurvedic clinicians can pinpoint the exact site and nature of the pathology, thereby implementing holistic treatments that address the root cause, strengthen or reduce the affected tissues, and harmonize overall doṣa-dhātu-mala balance.
