'''Attapulgite''' koloid aktif adalah [[magnesium]] alumunium silikat alamiah yang telah dimurnikan dan diaktifkan dengan cara pemanasan untuk meningkatkan kemampuan adsorpsinya. Berupa [[serbuk]] sangat halus, mempunyai [[pH]] antara 7,0-9,5. Attapulgite koloid aktif yang memiliki daya adsorpsi digunakan sebagai ''adsorben'' pada pengobatan [[diare]].
Pectin adalah karbohidrat yang berasal dari buah citrus atau [[apel]] yang telah dimurnikan. Pectin digunakan dalam pengobatan diare, biasanya dalam kombinasi dengan adsorben lainnya. Attapulgite maupun pectin diklaim dapat mengadsorpsi [[toksin]], gas, [[bakteri]], dan [[virus]] yang terdapat dalam lumen [[usus]].
