Ayurveda's Treatment Classification

Treatments in Ayurveda are classified into two groups:
I) Shamana Chikitsa (Pacification therapy)
II) Shodhana Chikitsa (Purification therapy)

Pancha Karma is classified as “Shodhana Chikitsa” (purification/detoxification procedure)
...Shodhana: Purification If
the doshas are vitiated beyond a particular level, they give rise to
various endo-toxins (Ama), which have a tendency to be accumulated in
the minute channels (Srotas) These endo-toxins (Ama) are
beyond the level of pacification and hence they need to be eliminated
from the body through Sodhana therapy Ayurveda recommends purification therapy for the majority of chronic diseases.
SEASONAL PANCHAKARMA
1.In autumn (Vata season), Basti (medicated enema) is recommended to
alleviate the normal aggravation of vata caused by the cold wind,
dryness of the season
2. In summer (Pitta season), Virechana (induced purgation) is given to remove excess pitta dosha, caused by excessive heat
3. In spring (Kapha season), Vamana (induced emesis) & Nasya (nasal
therapy) is performed to remove excess kapha caused by the coolness and
dampness of the season
