These are certain natural ingredients that are known to relieve symptoms of melancholy, including quiet mood, weepiness, and somber demeanor.
Ignatia amara (6C) is native to South East Asia but mostly the Philippines. This small tree provides a helpful remedy, proved by Dr. Hahnemann. Ignatia is particularly suited to those who are artistic and creatively inclined. They can be idealistic but tend not to express their feelings. Although they seem controlled and reserved, they can be emotionally fragile, often feeling elated and sad simultaneously. Those that fall in love easily, love very deeply, and suffer prolonged grief that they feel they may never recover from would likely benefit from Ignatia. Physical symptoms of an inner grief are frequent sighing, sensitivity to pain, and the ability to cry while simultaneously trying to ‘laugh it off’.
Kali. phosphoricum (D6) is one of the Schussler tissue salts, introduced as a biochemic tissue salt in the late nineteenth century. This remedy was proved by Dr. Allen, and is suited to those who are hard-working with practical ideas and a strong sense of morality. Those who become exhausted very easily and are easily upset by bad news (even if it does not affect them directly) would benefit from Kali phos.
Nat. sulphuricum (D6) (Sodium sulphate) is found naturally in seawater and in hot springs, and was introduced to as one of the Schussler salts.
This remedy is specifically beneficial to those who have a high sense of responsibility and a very sensitive nature – often easily driven to tears by sad movies, books, or music. When well, they are even-keeled and sensible, but a little reserved and aloof.
Staphisagria (6C) (Delphinium staphisagria) is a species of Larkspur native to the Mediterranean, and parts of Asia and Europe. The remedy was proved by Dr. Hahnemann. Staphisagria is best suited to those that tend to bottle up their emotions and often find it hard to say no. Those that physically tend to be very sensitive to pain (a low pain threshold) and perspire when nervous would likely benefit from Staphisagria.
