1. A hemostatic device comprising: an absorbent material;a composition comprising a clay hemostatic agent and hydroxypropylmethylcellulose;wherein the clay hemostatic agent is kaolin;wherein the composition is suspended in a liquid to form a suspension;wherein the suspension is absorbed onto the absorbent material during preparation of the hemostatic device; andwherein the clay hemostatic agent comprises about 10% or less of the weight of the suspension. 2. The hemostatic device of claim 1, wherein the absorbent material is selected from the group consisting of a sponge, a cloth, and a gauze. 3. The hemostatic device of claim 1, wherein the hemostatic device further comprises one or more of bentonite, montmorillonite, saponite, polygorskite or attapulgite, and sepiolite. 4. A hemostatic device comprising: an absorbent material;a composition comprising a clay hemostatic agent and a thickening agent selected from the group consisting of hydroxypropylmethylcellulose, methylcellulose, and hydroxypropylcellulose;wherein the clay hemostatic agent is kaolin; andwherein the composition is suspended in a liquid and absorbed onto the absorbent material during preparation of the hemostatic device. 5. The hemostatic device of claim 4, wherein the absorbent material is selected from the group consisting of a sponge, a cloth, and a gauze. 6. The hemostatic device of claim 4, wherein the hemostatic device further comprises one or more of bentonite, montmorillonite, saponite, polygorskite or attapulgite, and sepiolite. 7. The hemostatic device of claim 4, wherein the thickening agent is a gelling agent. 8. The hemostatic device of claim 4, wherein the thickening agent is hydroxypropylmethylcellulose. 9. A hemostatic device configured to halt the flow of blood from a bleeding wound, the hemostatic device comprising: an absorbent gauze;a hemostatic clay applied to the gauze such that the clay is configured to be dispensed onto a bleeding wound when the hemostatic device is applied to the bleeding wound;a composition comprising hydroxypropylmethylcellulose applied to the gauze;wherein the hemostatic clay comprises kaolin; andwherein the gauze is not saturated with liquid such that the gauze is capable of absorbing blood when the hemostatic device is applied to a bleeding wound. 10. The hemostatic device of claim 9, wherein the hemostatic device is dry. 11. The hemostatic device of claim 9, wherein the hemostatic device is provided in a sterilized package. 12. The hemostatic device of claim 9, wherein the hydroxypropylmethylcellulose acts as a thickening agent.
