KOSHTHA TO SHAKHA GATI OF DOSHA (कोष्ठात् शाखां गतिः)
Definition:
Movement of Doṣhas from Koṣṭha (gastrointestinal tract) to Śākhā (peripheral tissues) is called Koṣṭhāt Śākhā Gati.
It indicates the beginning of Dosha spread (Sañchāra) outside the GI tract.
Cause / Nidāna:
Improper management of Sañchaya (accumulation) and Prakopa (aggravation) stages.
Factors that obstruct the natural downward movement of Doṣhas, such as:
Suppression of natural urges
Improper administration of purification therapies
Indulgence in causative factors even after symptoms start
Mechanism:
When aggravated Doṣhas in the Koṣṭha are not expelled, they overflow and move to the Śākhā.
This movement marks the Prasara Avasthā (spreading stage) of disease development.
Relevant Śloka (from Ashtanga Hridaya, Sutrasthana, Chapter 1):
"संचयं च प्रकॊपं च प्रशमं चापि यॊऽन्विति।
स रोगमक्षतं वेत्ति स च विज्ञेय भिषग्वरः॥"
(AH Su.1/25)
Pathophysiology:
Vāta pushes the aggravated Doṣhas into circulation.
These Doṣhas then lodge in Rasa, Rakta, Mamsa, Meda, etc.
Leads to prodromal symptoms (Pūrvarūpa) or localized disease manifestation.
Clinical Examples:
Ama Vāta – Vāta takes Ama (toxins) to joints (Śākhā).
Vāta Rakta – Doṣhas reaching Rakta dhātu and small joints.
Signs & Symptoms:
Discomfort shifts from GI tract to peripheral parts.
Symptoms become localized – e.g., joint pain, skin rashes, etc.
Sometimes, GI symptoms reduce while peripheral symptoms appear.
Definition:
Movement of Doṣhas from Śākhā (periphery) back to Koṣṭha (gut) is called Śākhāt Koṣṭha Gati.
Also called Saṅghāta Mokṣa or Pāchana Mārga, depending on context.
Purpose:
Makes Doṣhas ready for elimination (Shodhana).
Indicates a favorable shift in disease – sign of ripening of disease (Pakva Avasthā).
Indications:
When Doṣhas return to GI tract, Shodhana therapies like Vamana, Virechana can be administered.
Return to Koṣṭha indicates accessibility of Doṣhas for expulsion.
Mechanism:
Proper digestion (Agnibala), use of Deepana-Pāchana medicines and Langhana (fasting/light food) helps draw Doṣhas back to Koṣṭha.
Relevant Śloka (Ashtanga Hridaya, Sutrasthana, Chapter 13):
"शुद्धे कोष्ठे स्थितान् दोषान् संसृष्टानपि सात्म्यजः।
निश्चिन्त्य बहिर्नयेत् स्वेदवमनविरैचनैः॥"
(AH Su.13/26)
Factors Supporting Return to Koṣṭha:
Use of Langhana (lightening therapy)
Administration of Deepana-Pāchana herbs (appetite and digestion-enhancers)
Improved Agni (digestive fire)
Cessation of aggravating factors
Restoration of proper Vāta function (Prāṇa, Apāna balance)
Clinical Relevance:
Purgative Therapy becomes effective only after Doshas return to Koṣṭha.
Delayed Shodhana in stage of Śākhā gati is contraindicated.
Shodhana performed prematurely in Śākhā gati may worsen the disease.
Signs of Doshas Having Returned to Koṣṭha:
Increase in GI symptoms again (nausea, heaviness, distension).
Reduction in peripheral symptoms.
Improved signs of appetite and elimination.
