Diluent in the context of "Homeopathy"

A paint thinner is a solvent used to dilute oil-based paints or varnish. In this context, to dilute is also known as to 'thin'. Paint thinners are diluents. Solvents labeled "paint thinner" are usually white or mineral spirits.

A concentrate is a form of substance that has had the majority of its diluting agent or diluent (in the case of a liquid: the solvent) removed, such that the substance becomes the majority of the composition. Typically, this will be the removal of water from a solution or suspension, such as the removal of water from fruit juice.

A tablet (also known as a pill) is a pharmaceutical oral dosage form (oral solid dosage, or OSD) or solid unit dosage form. Tablets may be defined as the solid unit dosage form of medication with suitable excipients. It comprises a mixture of active substances and excipients, usually in powder form, that are pressed or compacted into a solid dose. The main advantages of tablets are that they ensure a consistent dose of medicine that is easy to consume.

Tablets are prepared either by moulding or by compression. The excipients can include diluents, binders or granulating agents, glidants (flow aids) and lubricants to ensure efficient tabletting; disintegrants to promote tablet break-up in the digestive tract; sweeteners or flavours to enhance taste; and pigments to make the tablets visually attractive or aid in visual identification of an unknown tablet. A polymer coating is often applied to make the tablet smoother and easier to swallow, to control the release rate of the active ingredient, to make it more resistant to the environment (extending its shelf life), or to enhance the tablet's appearance.
