Kapha also embodies the watery energies of love and compassion. This dosha hydrates all cells and systems, lubricates the joints, moisturizes the skin, maintains immunity, and protects the tissues.
When out of balance, kapha triggers emotions of attachment, greed, and possessiveness and can also create stubbornness, lethargy, and resistance to change. Physically, kapha tends to invite stagnation and congestion in organs and tissues throughout the body - including the mind.
Foods that increase kapha are, in general, sweet, sour, and salty in taste. These tastes, if in excess for the kapha in your prakruti (constitution), can create heavy, sluggish, and wet digestion. According to ayurveda, this will cause digestive hardship for kapha and an eventual range of imbalances.
