Abstract
Abstract A composition for treating teeth comprising from about 10% to 20% by weight of blood root, approximately 58 to 158 by weight of powdered galangal root, and about 70% to 80% by weight of liquified zinc chloride in a suitable carrier for oral use. The composition is prepared by thorough admixture of the components under controlled conditions and aged before use. The composition may be applied to the teeth by means of a carrier such as a toothpaste, toothpowder, lozenges or mouthwash.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
103 words
A method for preparing a composition for treating teeth to reduce bacterial growth thereon comprising the steps of: a. exposing crystalline zinc chloride to air to liquify the same, b. mixing together about 10% to 20% by weight of powdered blood root and about 5% and 15% by weight of powdered galangal root to about 70% to 80% by weight of liquified zinc chloride; and c. intermittently and thoroughly mixing together the liquified zinc chloride and the mixture of powdered blood root and powdered galangal root over a period of time sufficient to permit aging of the mixture including solution of soluble components.
Claim 2
Independent Claim
103 words
A method for preparing a composition for treating teeth to reduce bacterial growth thereon comprising the steps of: a. exposing crystalline zinc chloride to air to liquify the same, b. mixing together about 10% to 20% by weight of powdered blood root and about 5% and 15% by weight of powdered galangal root to about 70% to 80% by weight of liquified zinc chloride; and c. intermittently and thoroughly mixing together the liquified zinc chloride and the mixture of powdered blood root and powdered galangal root over a period of time sufficient to permit aging of the mixture including solution of soluble components.
Claim 3
Dependent Claim
24 words
The method of claim 1 wherein the mixing and aging are carried out in the absence of direct sunlight and in metal free receptacles.
Claim 4
Dependent Claim
26 words
The method of claim 1 wherein the mixing and aging are carried out in the presence of humid air at a temperature of about 74° F.
Claim 5
Independent Claim
106 words
A method for preparing a composition for treating teeth to reduce bacterial growth thereon comprising the steps of: a. mixing crystalline zinc chloride with sufficient water to form liquified zinc chloride; b. mixing together about 10% to 20% by weight of powdered blood root and about 5% to about 15% by weight of powdered galangal root to about 70% to 80% by weight of liquified zinc chloride and c. intermittently and thoroughly mixing together the liquified zinc chloride and the mixture of powdered blood root and powdered galangal root over a period of time sufficient to permit aging of the mixture including solution of soluble components.
Claim 6
Independent Claim
106 words
A method for preparing a composition for treating teeth to reduce bacterial growth thereon comprising the steps of: a. mixing crystalline zinc chloride with sufficient water to form liquified zinc chloride; b. mixing together about 10% to 20% by weight of powdered blood root and about 5% to about 15% by weight of powdered galangal root to about 70% to 80% by weight of liquified zinc chloride and c. intermittently and thoroughly mixing together the liquified zinc chloride and the mixture of powdered blood root and powdered galangal root over a period of time sufficient to permit aging of the mixture including solution of soluble components.
Claim 7
Dependent Claim
20 words
The method of claim 4 wherein aging is conducted at a temperature from about 55° C. to about 65° C.
Claim 8
Dependent Claim
99 words
A composition for treating teeth to reduce bacterial growth thereon consisting essentially of a composition prepared by the following process: a. exposing crystalline zinc chloride to air to produce liquified zinc chloride; b. mixing together about 10% to 20% by weight of powdered blood root and about 5% to 15% by weight of powdered galangal root to about 70% to 80% by weight of liquified zinc chloride; and c. thoroughly mixing together the liquified zinc chloride and the mixture of powdered blood root and powdered galangal root over a period of time sufficient to permit aging of the mixture.
Claim 9
Dependent Claim
99 words
A composition for treating teeth to reduce bacterial growth thereon consisting essentially of a composition prepared by the following process: a. exposing crystalline zinc chloride to air to produce liquified zinc chloride; b. mixing together about 10% to 20% by weight of powdered blood root and about 5% to 15% by weight of powdered galangal root to about 70% to 80% by weight of liquified zinc chloride; and c. thoroughly mixing together the liquified zinc chloride and the mixture of powdered blood root and powdered galangal root over a period of time sufficient to permit aging of the mixture.
