Here are the Provings of OPIUM from the Materia Medica of Homeopathic Medicine,By Dr William Boericke MD :-

OPIUM

(PAPAVER SOMNIFERUM)

Hahnemann says that it is much more difficult to estimate the action of Opium than of almost any other drug. The effects of Opium as shown in the insensibility of the nervous system, the depression, drowsy stupor, painlessness, and torpor, the general sluggishness and lack of vital reaction, constitute the main indications for the drug when used homeopathically. All complaints are characterized by sopor. They are painless, and are accompanied by heavy, stupid sleep, stertorous breathing. Sweaty skin. Dark, mahogany-brown face. Serous apoplexy-venous, passive congestion. Want of sensitiveness to the action of medicines. Reappearance and aggravation from becoming heated. Opium lessens voluntary movements, contracts pupils, depresses higher intellectual powers, lessens self-control and power of concentration, judgment; stimulates the imagination, checks all secretions except that of the skin. Want of susceptibility to remedies even though indicated. Diseases that originate from fright.

Mind.--Patient wants nothing. Complete loss of consciousness; apoplectic state. Frightful fancies, daring, gay, bright. Unable to understand or appreciate his sufferings. Thinks he is not at home. Delirious talking, with wide open eyes.

Stomach.--Vomiting, with colic and convulsions. Fecal vomiting. Incarcerated hernia. Hungry; no desire to eat.

Abdomen.--Hard, bloated, tympanitic. Lead colic during colic, urging to stool and discharge of hard feces.

Stool.--Obstinate constipation; no desire to go to stool. Round, hard, black balls. Feces protrude and recede (Thuj; Sil). Spasmodic retention of feces in small intestines. Stools involuntary, black, offensive, frothy. Violent pain in rectum, as if pressed asunder.

Urine.--Slow to start; feeble stream. Retained or involuntary, after fright. Loss of power or sensibility of bladder.

Female.--Suppressed menses from fright. Cessation of labor-pains with coma between paroxysms. Threatened abortion and suppression of lochia, from fright, with sopor. Horrible labor-like pains in uterus, with urging to stool.

Respiratory.--Breathing stops on going to sleep; must be shaken to start it again (Grindelia). Hoarse. Deep snoring; rattling, stertorous breathing. Difficult, intermittent, deep, unequal respiration. Heat in chest; burning about heart. Cough, with dyspn艙a and blue face; with bloody expectoration.

Sleep.--Great drowsiness (Gels.; Nux mosch). Falls into a heavy stupid sleep. Profound coma. Loss of breath on falling asleep (Grind). Coma vigil. Picking at bedclothes. Very sleepy, but cannot go to sleep. Distant noise, cocks crowing, etc, keep him awake. Child dreams of cats, dogs, black forms. Bed feels so hot cannot lie on it. Pleasant, fantastic, amorous dreams. Shaking chill; then heat, with sleep and sweat. Thirst only during heat.

Skin.--Hot, damp, sweating, Constant desire to uncover. Hot perspiration over whole body except lower limbs.

Modalities.--Worse, heat, during and after sleep (Apis; Lach.). Better, cold things, constant walking.

opium poppy plants..

Opiates are derivatives of poppies and it's probably illegal, so I'll be checking back on this to see if someone with more knowledge on this subject can give you an answer about something that isn't illegal.

none

I think you may be using the word "homeopathic" incorrectly. Do you mean natural sources? If so, then the answer is poppies (Papaver somniferum). Homeopathic refers to the modality/preparation of remedies and is not the same as naturopathic or herbal.
