In sutra sthana acharya explains about the best dravyas. There he says the आनूप देश is the best in अहित देशs and मरुभूमि is the best आरोग्यजनक desha.

Astanga Sangraha:

According to vagbhata also the lands are of three types:

1. Jangala desha - This has vata as predominant dosha
2. Anupa desha -  This has kapha as predominant dosha
3. Sadharana desha - This has all three doshas  in their balanced state.

Jangala desha:

The features found in jangala desha are just opposite to that of anupa desha. This type of land shows the features like uneven surfaces, large areas covered with sand, tasteless water on digging the land deep and strong, healthy, deerghayu (long life) people. This land is the origin of katu rasa.

Anupa desha:  

The features of anupa desha are - this land has cool gentle breeze, thick forest, the river and the ponds are covered with kamala, kumuda, kuvalaya. The land is covered with thick green grass, the trees are completely covered by creepers, one can see lot of snakes, birds in this area.  This land has predominance of kapha and pitta. The water and medicines of this area are heavy (guru) in nature. People here suffer from diseases like shleepada, galaroga, apachi, jwara, etc.  Anupa desha is the origin for madhura rasa (sweet taste).

Sadharana desha:

The combination of anupa and jangala desha. There are two types of sadharana desha.

1. Anupa sadharana desha - This is the origin of lavana rasa and amla rasa
2. Jangala sadharana desha - This is the origin of tikta and kashaya rasa.

While explaining the best dravyas vagbhata says मरुभूमि देश is the best desha for आरोग्य (health), the ahita desha is anupa desha.

Note:

1. The examples for jangla desha are Marvad region
2. The example for anupa desha is Bengal
